How it works

- Classic fixed-size Renko is built internally from BID ticks.

- Reversals use the classic two-brick rule.

- The Donchian channel is calculated from the previous N completed Renko bricks.

- The current brick is excluded from the channel calculation, avoiding look-ahead.

- A bullish Renko brick closing above the previous Donchian high can trigger BUY.

- A bearish Renko brick closing below the previous Donchian low can trigger SELL.

- Positions close by TP, SL, opposite Donchian breakout, or maximum holding time.

- A short Renko cooldown can be used after an exit.

- One position per symbol.

- No external indicators, DLLs, custom symbols or offline Renko charts are required.
