A forex trading journal is a trading journal that records, on top of the result, what is specific to the currency market: the session, the pair and the currency it shares with your other pairs, the spread, the swap, the size in units and the leverage. Forex has a quiet statistical trap: two pairs quoted against the same currency give the illusion of diversified edge, when a single market move may simply have been counted twice. Add to that hours when activity and spread change completely, and costs that eat into tight pip targets, and you get a market that, without a journal built for it, hides as much as it reveals.
- Session tagging (Sydney, Tokyo, London, New York, overlaps) shows whether your edge holds at every hour, in a market whose activity and spread change through the day.
- Correlated pairs artificially inflate your real exposure if you don't track them together.
- Spread and swap bite proportionally harder into tight pip targets.
- Pip-based vs percentage-based sizing: two different logics you should choose consciously, not by default.
Forex lends itself to a minimalist journal, pair, direction, result, precisely because the market's mechanics seem simple at first glance. That's a mistake that costs money: forex has its own sources of statistical bias, largely invisible unless your journal explicitly captures them. For how the market itself works, see what forex trading is and the Academy lesson on the forex market.
This guide details the fields and tracking habits that make the difference between a forex journal that actually tells you something about your edge, and one that piles up rows without ever revealing the real mechanics of your performance. If pip, lot or leverage are still fuzzy words, start with our forex trading lessons for beginners.
Why this much rigor? Because regulators have counted. The study by the AMF, the French regulator, of 14,799 active clients in France, followed over four years between 2009 and 2013, finds more than 89% of losing clients on CFDs and forex, and ESMA, the European markets regulator, reports that 74-89% of retail accounts lose money on CFDs in the countries analysed by national authorities. Those figures say nothing about the effect of a journal, and we know of no study that measures it on forex traders. What has been measured is the effect of monitoring a goal in general: the meta-analysis by Harkin and colleagues, published in 2016 in Psychological Bulletin, pools 138 experimental studies and 19,951 participants, who are not traders, and concludes that monitoring your progress helps you reach your goal, more so when the information is physically recorded. That is the underlying reason for keeping a trading journal, and for logging the fields that follow.
Session tagging, the first blind spot to close
The currency market runs continuously from Monday to Friday, but not at the same intensity. The 2025 Triennial Survey of the Bank for International Settlements places approximately 38% of trading in the United Kingdom and 19% in the United States: London and New York hours weigh more than the others. On interbank transactions from the EBS platform between 1999 and 2001, Ito and Hashimoto (NBER, 2006) find three activity peaks on EUR/USD and USD/JPY, at the Tokyo open, in the London morning and when the London afternoon overlaps the New York morning, a spread at its narrowest during that overlap and at its widest between 18:00 and 22:00 GMT, late in the US day, and a Tokyo market, like the Asian session in general, that counts for little in euro trading. The study also finds that volume and volatility move together: the market is more volatile in the hours when it is most active. Those measurements are old and describe the interbank market, not your broker's prices. They are enough to raise the question: the same setup isn't taken under the same conditions depending on the session. The hours of each one are in the Academy lesson on trading sessions and killzones.
Without an explicit 'session' field in your journal, you simply can't answer a question as basic as 'am I better on London or New York?' Once your trades are tagged, the split of your losses by time window becomes readable, and you can see whether one of them concentrates a significant share, for instance the one you trade out of habit rather than real edge.
Correlated pairs: a risk hiding in plain sight
Some pairs tend to move in the same direction or in opposite directions, because they share a common currency or closely related economic dynamics. The common currency is most often the dollar: according to the same BIS survey, it was on one side of 89.2% of all trades in April 2025. EUR/USD and GBP/USD, for example, are both quoted against it, so buying both amounts to selling the dollar twice. It's not an absolute rule, the strength of that relationship varies over time and is measured on your own trades, but it's reason enough for every forex trader to account for it.
The trap is believing that opening three positions on three different pairs diversifies your risk, when in reality, if those pairs are correlated, you may have taken the same dollar bet three times over, with three times the risk you think you took. Without tracking that groups your open positions by underlying currency, this risk concentration stays invisible until the day a single market move hits all three positions at once.
Spread and swap: costs that eat into small targets
On a target of a few dozen pips, the spread, which the National Futures Association's guide to retail forex defines as the point or pip difference between the ask and bid price of a currency pair, weighs proportionally far more than on an instrument with wider average moves. A two-pip spread on a twenty-pip target represents 10% of your target. In money, on 100,000 euros of EUR/USD, one pip is worth 10 dollars (the same guide counts 50 dollars for five pips on that size): the spread costs 20 dollars for a 200-dollar target. Redo that calculation for your pair and your size with the pip value calculator, and log the spread paid next to each trade.
| Cost | What it represents |
|---|---|
| Spread | Cost paid on entry and/or exit, heavier on small targets |
| Swap (rollover) | Cost or gain from holding overnight, tied to the interest rate differential between currencies |
| Commission | Per-trade fee some dealers charge, instead of or on top of a mark-up on the spread |
| Slippage | Gap between the intended price and the actual execution price |
Two of these lines vary from one broker to another. The NFA guide points out that a dealer can charge a per-trade commission, widen the spread it gets from a bank itself, or do both: that line is to be read in your account's terms. Slippage, which the broker IG's page on slippage, a broker source to be read as such, defines as an order being executed at a price that doesn't match the requested price, is measured by logging the intended price next to the price you got.
Swap, the cost or gain tied to holding a position overnight, comes from rolling the position over: the NFA guide explains that most dealers charge a rollover fee based on the interest rate differential between the pair's two currencies. It isn't the same for buys and sells: MetaTrader 5's documentation on symbol specifications separates a swap long from a swap short, and a multiplier for each day of the week, with one day when the swap is charged three times (the night from Wednesday to Thursday in its example). On strategies that hold positions for several days, this accumulated factor deserves separate tracking from price result, exactly like funding on crypto perpetuals. Ignoring these costs overstates your real edge.
It is also a cost a spreadsheet easily forgets, because it appears neither in your entry price nor in your exit price. If you keep your journal by hand, the forex section of the Excel trading journal template details the three columns to add so that swap, pip value and lot size stop skewing your statistics.
Pips or percentage: a choice to make consciously
Forex offers two measurement logics that rarely coexist well in the same journal unless you explicitly choose which one takes priority for you. Pip-based measurement gives a direct, familiar read of price movement, useful for judging a setup's execution quality. Percentage-of-capital measurement brings everything back to the same denominator, your real risk, and lets you compare trades taken with different position sizes.
The problem shows up when a trader reasons purely in pips without ever tying that number back to their real percentage risk: two twenty-pip winning trades can represent totally different risk levels if position size wasn't the same. The right move is keeping both pieces of information, pips for the technical read, percentage or R-multiple for the risk read, rather than picking one over the other.
Leverage, more present in forex than elsewhere
Leverage lets you control a much larger position than the capital actually deposited, and the European caps on CFDs are highest on currencies. In the European Union, ESMA's measures on CFDs, announced in March 2018, cap a retail client's leverage at 30:1 on major currency pairs and 20:1 on the others, against 5:1 on individual equities and 2:1 on cryptocurrencies, and the AMF applies them in France through national measures (page in French) since 1 August 2019. In the United Kingdom, the FCA's rules on CFDs have set limits of between 30:1 and 2:1 depending on the asset since the same date. In the United States, Section 12 of the NFA's Financial Requirements sets the retail forex security deposit at 2% of notional value on ten currencies, including the euro, the yen and the British pound, which is 50:1 leverage, and at 5% on the others, which is 20:1. Elsewhere the rules differ: log in your journal which regulator your account falls under. Leverage amplifies both gains and losses, which makes tracking position size, in lots and in percentage of capital risked, particularly important so you don't underestimate your real exposure. Our article on what leverage is in trading details the caps product by product.
A forex journal that only logs the result in currency without ever tying that result back to the leverage and size actually used gives an incomplete picture of the risk taken. Log the size in units too: MetaTrader 5's documentation defines contract size as the number of units in one lot, and it is read in each symbol's specification. That's especially true for traders who vary their position size from trade to trade based on conviction, a practice that can be legitimate but that needs to be tracked explicitly to be judged objectively. The method for calculating position size starts from the risk you accept, not from the leverage on offer.
Economic announcements, a context to tag
Forex reacts to scheduled macroeconomic announcements, rate decisions, employment figures, inflation. On six years of real-time quotations of the dollar against the German mark, the British pound, the yen, the Swiss franc and the euro, Andersen, Bollerslev, Diebold and Vega (NBER, 2002) show that it is the surprise, the gap between the expected figure and the published one, that makes the rate jump, and that the market reacts more to bad news than to good news. A trade taken right before or during that kind of announcement doesn't carry the same risk profile as a trade taken under normal market conditions, even if the initial technical setup was identical.
Tagging trades taken near a major economic announcement in your journal lets you check whether your strategy genuinely holds up in that kind of context, or whether it simply benefited once from a lucky move that validated a stop that was too wide. That tag is also what lets you objectively distinguish a strategy built to trade these announcements, which should be judged with its own yardstick, from a classic technical strategy that should probably avoid them instead.
Major, minor and exotic pairs: different conditions
Not all currency pairs offer the same liquidity or behavior. Major pairs set the US dollar against the most traded currencies, and activity concentrates there: in the 2025 BIS survey, the euro is on one side of 28.9% of all trades, the yen 16.8% and sterling 10.2%. And the spread follows activity: in the Ito and Hashimoto measurements cited above, it is narrower when transactions are more numerous. Minor pairs, and especially exotic pairs, which involve less traded currencies, are therefore exposed to a wider spread, more irregular liquidity depending on the hour, and sometimes more erratic moves. The line is regulatory too: in the European Union, the leverage cap isn't the same for a major pair and for the others.
A journal that logs the category of pair traded (major, minor, exotic) lets you check whether your technical edge genuinely holds up on pairs with tougher conditions, or whether it only works well on the most liquid pairs where execution is cleanest. It's a useful distinction before extending a strategy tested on EUR/USD to less common pairs while wrongly assuming market behavior will be identical.
If your forex broker gives you an account on MetaTrader, also note in your journal the account's position accounting mode, netting or hedging: it changes the way a trade gets closed. The guide What is MT5? explains the difference.

Frequently asked questions
Why tag my forex trades by session?
Because the currency market's activity and spread change with the session (Sydney, Tokyo, London, New York, overlaps): measurements made on the interbank market show a narrower spread when London and New York are open together, and a wider one late in the US day. The same setup is therefore not taken under the same conditions depending on the hour. Without this tag, you can't tell whether your performance depends heavily on when you trade.
What is correlation between currency pairs and why track it?
Two pairs that share a currency, like EUR/USD and GBP/USD with the dollar, partly carry the same bet, and their moves can look alike for long stretches. Taking several positions on correlated pairs can mean taking the same bet multiple times without realizing it, inflating your real risk beyond what you think.
Does spread really hurt my small pip targets?
Yes, proportionally more than on an instrument with wider average moves. A two-pip spread on a twenty-pip target already represents 10% of the target, before any commission or swap. The calculation is done once per pair and logged in the journal.
Should I measure my forex performance in pips or percentage?
Both, for different purposes. Pips give a direct read of price movement and setup execution quality. Percentage of capital (or the R-multiple) brings everything back to the same denominator, the real risk taken, letting you compare trades taken with different position sizes.
What is swap in forex and why track it?
It's the cost or gain from holding a position overnight, depending on the interest rate differential between the pair's two currencies. It differs for buys and sells, and one day a week it is charged three times. On strategies that hold positions for several days, this accumulated factor deserves separate tracking from price result so it doesn't distort your real edge.
How does Tradoshi import my forex trades?
Through a direct connection to your MT4/MT5 accounts with a read-only investor password, or via CSV import for any broker not natively connected. Your statistics are then computed automatically, including multi-currency handling if your account is denominated in a currency different from yours.
Should I tag trades taken during an economic announcement?
Yes. A trade taken right before or during a major macroeconomic announcement doesn't carry the same risk profile as a trade taken under normal market conditions. This tag lets you check whether your strategy genuinely holds up in that context or simply benefited once from luck.
Does the pair category (major, minor, exotic) affect my performance?
It changes your execution conditions, so it can change your result. The most traded pairs have the narrowest spread, while minors and exotics are exposed to a wider spread and more irregular liquidity. Tracking this category lets you check whether your edge holds up on pairs with tougher conditions.
Does it matter whether the account is demo or live for what I should track?
The journal's content doesn't fundamentally change, but a demo account doesn't send your orders to the real market: slippage, the gap between the requested price and the executed price that appears when the price moves fast, can be absent or different there. Keeping that difference in mind avoids overestimating an edge validated only in demo.
Should I log the account type (standard, ECN, cent) with my broker?
It's useful, because the way the broker gets paid changes from one account to another: a per-trade commission, a mark-up added to the spread, or both. The leverage granted can differ too. Comparing two performances without distinguishing these structures can distort the real read of your transaction costs.
Does the day of the week really affect my forex performance?
One effect at least is mechanical: swap is charged three times one day a week, the day set in the instrument's specification at your broker. Beyond that, a Monday waiting for direction or a Friday of profit-taking are hypotheses to test on your own trades, not established rules. Tagging the day of the week, alongside session, is precisely how you check.
