What Is Profit Factor in Trading?

Win rate tells you how often you were right. Profit factor tells you whether being right paid for being wrong. Only one of those keeps an account alive.

As Chad puts it about higher timeframe trades, "On lower time frames, you're really catching your profits on volume, but on these you're catching it on risk to reward ratios and duration."

How do you work out profit factor?

Add up the dollar gains of every winner, add up the dollar cost of every losing trade, and divide the first by the second. Winners made $6,000 and losing trades cost $5,000? Profit factor is 1.2.

With a fixed dollar risk per trade it's simpler to work in R, where 1R is the planned risk. At a 1:3 risk to reward, one win in four gives 3R of gains against 3R of stops: a profit factor of exactly 1.0, which is break even. Three wins in ten gives 9R against 7R, about 1.29. Costs pull every one of those down, because fees and funding shave each winner and add to each stop.

It's a close relative of expectancy, the average result per trade. Profit factor gives you the ratio. Expectancy gives you the size.

Can a high hit rate have a losing profit factor?

Absolutely. Two hypothetical sets of 20 trades, with trading costs of 0.1R per trade included at the end.

Set one, every trade planned at 1:3. Six trades reach target for 18R, two are closed early at 0.5R each for 1R, and twelve hit the stop for 12R. Gross profit 19R, gross loss 12R: a profit factor of 1.58 before costs. With costs taken off the eight winners and added to the twelve stops, it becomes 18.2R against 13.2R, about 1.38.

Set two, small targets and a high hit rate. Fourteen trades close at 0.5R for 7R and six hit the stop for 6R. Before costs the profit factor is 1.17, which looks fine. After costs it's 5.6R against 6.6R, about 0.85. Below break even, despite winning most trades.

Both sets are illustrative, not results. Set two won 14 of 20 and still went backwards. Small winners leave no room for costs, and profit factor is where that shows up first.

When does profit factor get checked?

In the review step, the last of seven in the Decision Protocol. The earlier steps make the number mean something. The 1:3 filter fixes the shape of every trade, so you know in advance that one target in four is break even. A fixed dollar risk, 1 to 2% while you're new, keeps every R the same size, so one oversized position can't distort the figure.

Chad's version: "Trading takes consistency of variables. We wanna be very, very consistent with our variables." Measured that way, profit factor compares your own setups. Split the journal by setup, say sweeps of equal lows against trendline retests, and the weaker figure is the one to fix or drop.

We don't set a profit factor target for anyone, and we don't publish one. It measures your decisions, not a goal to trade toward. Anyone waving their number as a reason to buy? Ask for the journal behind it.

How do traders fool themselves with profit factor?

Too few trades. Five trades with one big winner can show a profit factor of 3 or more and mean absolutely nothing. Wait for at least 20 to 30 trades of the same setup.

Letting risk vary. If one trade risked 4% and the rest risked 1%, that single trade decides the whole figure, and you're measuring your sizing, not your setups.

Leaving out costs. On small targets, fees and funding are often the difference between above 1.0 and below it.

What profit factor check should you run this week?

Take your last 20 trades and do the division. Then do it again with 0.1R of costs per trade. If the second number scares you... good. That's the journal doing its job.

Profit factor sits with the other risk numbers in crypto risk management. For the seven decisions that produce the trades it's calculated from, read the Decision Protocol guide. See also win rate.
