Biggest win / Biggest loss

These are the best and worst results on a single trade over the period. Two isolated values that summarise nothing, and yet say more about your discipline than most averages: averages smooth things out, extremes show what happened the day it went off the rails.

The formula

The best and worst result on a single trade.

How to read it

Your extremes. A biggest loss far above your average = a blown stop.

Compare your biggest loss to your average loss. If it is twice as large, a stop was widened or pulled. If it is five times as large, there was none. No other reading is needed: that ratio speaks for itself, and it points at the exact trade to reopen in your journal.

The classic mistake

Treating your biggest winner as proof of skill. It is often the opposite: a winner far above the rest signals an oversized position, so a risk that would have produced the same excess in the other direction. The same trade, reversed, would have been the biggest loss.
