Part 2 · lesson 3 of 3

You add up one whole losing trade, step by step.

About 6 minutes.

Whose numbers these are

You have not picked a firm yet. So the figures below come from one firm’s published rules. Each one is named and dated where it appears. Pick a firm and the same lesson runs on your own numbers.

One trade, from the entry to what it cost

Highest point reached: $50,180. What the account is worth now: $50,110.

  1. Start where the line sits: the best the account has been, less $2,000 The account closes if the balance falls $2,000 below the highest point it has ever reached.Apex Trader Funding $50K evaluation, floor moves on every new high — published rules read 2026-07-14, spec 1.2.0. $48,180
  2. Take that away from what the account is worth now. That is what one trade is spending from. $1,930
  3. Now say how much of that room you are willing to spend on being wrong once. The size follows from your answer, not the other way round.

Later in the course these steps arrive with more of the working removed, and you write it.

That is the end of this one.

Next: 2 questions you have not seen. Being wrong costs nothing.
