Renko Live Chart Strategy

This strategy emulates a classic Renko brick chart and trades on brick direction changes. It was converted from the MetaTrader script RenkoLiveChart_v600.

Logic

The strategy builds Renko bricks using finished time‑based candles. When the price moves by at least the selected box size from the last brick price, a new brick is formed. A long position is opened on an upward brick and a short position on a downward brick.

Parameters

  • Candle Type – timeframe of the input candles used for brick construction.
  • Brick Size – price step that defines the height of a Renko brick.
  • Brick Offset – initial offset in bricks applied to the first brick.
  • Show Wicks – display wicks on the chart when drawing candles.

Notes

  • Trades are executed only on completed candles.
  • Position protection is started automatically on strategy start.
  • This implementation focuses on core Renko behaviour and ignores advanced features of the original script, such as external file handling.
