Case Study, Tomas: Four Failed Evaluations and the Rules Nobody Read
Tomas is a composite character. He bought four funded-account evaluations at 250 dollars each, for 1,000 dollars, and failed all of them. He trades with 2 percent risk per trade, and the program allows a 5 percent daily loss and a 10 percent total drawdown.
Reconstruct the failures. At 2 percent per trade, three consecutive losses cost about 5.9 percent, which breaches the 5 percent daily limit in one bad morning. Five losses in a row cost 9.6 percent, close to the total limit.
How likely is a three-loss streak? At a 45 percent win rate, 0.55 cubed is 16.6 percent for any three consecutive trades. Over a typical evaluation with 60 trades, at least one such streak is almost certain, and the daily limit gets triggered.
What would a fitting risk be? To survive an eight-loss streak within a 10 percent drawdown, with a safety margin of 40 percent, the risk is about 0.75 percent per trade. Three consecutive losses cost 2.2 percent, comfortable for the daily limit.
At 0.75 percent, the profit target of 8 percent needs about 10.7R net. If expectancy is 0.2R per trade, that takes about 53 trades.
What about time? If trades arrive at five a week, that is eleven weeks. Tomas wanted to pass in two weeks, which forced larger risk.
Lesson. The rules define the maximum viable risk. Position sizing must start from the rules. Passing quickly and passing at all are different goals.
Practical change: simulate the evaluation on demo first with the firm's exact rules.
Exercise: compute the largest risk per trade that keeps a three-loss day within a 5 percent limit.
