The Metric You Chose Last Year Is Steering You Now

Three or four quarters after a reporting template is written, the number at the top of it has quietly become the objective. The note orb trading review consultoriainnova publishes on this covers that drift, because a strategy for the opening range is adjusted by whoever reads the report, and every adjustment is made in the direction that improves the headline figure. Selecting that figure is therefore a decision about the system itself rather than about presentation.

Win Rate Pulls Toward Short Targets

Put win rate at the top and every subsequent change will move the profit target closer, because a nearer target is hit more often. The percentage climbs quarter by quarter and the total result falls. Nothing in the review flags it, since the metric being reported is improving exactly as intended. This is the most common version of the problem and it takes a year to become obvious.

Total Result Pulls Toward Size

A headline of cumulative profit encourages larger position sizing, since that is the fastest way to move it. Risk per trade creeps up without any explicit decision, and the drawdown that eventually arrives is proportionally larger than anything in the history the review was built on. The metric was not wrong. It was simply incomplete without a risk figure beside it.

Expectancy per Trade Pulls Toward Fewer Trades

Optimising average result rewards filtering, and filtering reduces frequency. Taken far enough it produces a system with excellent numbers and four trades a quarter, which is unusable and also impossible to evaluate because the sample size never grows. Any metric expressed per trade needs a frequency figure printed next to it.

Use a Pair, and Fix Both

The workable arrangement is two numbers that pull in opposite directions, reported together and never separately. Total result against maximum drawdown. Expectancy against trade count. Win rate against average winner to average loser. A pair is much harder to game than a single figure, and improving one at the cost of the other is visible immediately rather than a year later.

Review the Metric Itself

Once a year the reporting template deserves the same scrutiny as the rules. Ask what behaviour the current headline has encouraged over the last four periods and whether that behaviour was intended. The answer usually explains more about how the trading plan has evolved than any individual change recorded in the log.
