Trading math, practised until it's automatic.

Risk, reward, position size, expectancy and drawdowns: drill the arithmetic, then use it on realistic simulated charts where the future is revealed one candle at a time.

How a simulator round works

  1. Pick a market. You see 30 sessions of history; the rest has not been generated yet.
  2. Plan a trade: set a stop by volatility (ATR), a target in R, and a risk percentage. The size is computed for you.
  3. Replay candle by candle on any timeframe. Stops, targets, gaps and slippage are filled minute by minute.
  4. Review: see your expectancy, and only then what the market's hidden regime really was.
