TPSL Insert Strategy

This strategy is a StockSharp translation of the MetaTrader 4 script TPSL-Insert.mq4. It does not generate entry or exit signals. Its only purpose is to attach take-profit and stop-loss orders to existing positions.

How It Works

  1. At start, the strategy reads TakeProfitPips and StopLossPips parameters.
  2. The values are converted from pips to price using the security's PriceStep.
  3. StartProtection is called to place protective orders.
    • If a position already exists, protective orders are sent immediately.
    • Future positions opened by the strategy will be protected automatically.

This behavior is useful when positions are opened manually or by external systems and you need to insert risk limits quickly.

Parameters

Name Description Default
TakeProfitPips Take-profit distance in pips. 35
StopLossPips Stop-loss distance in pips. 100

Notes

  • The strategy does not subscribe to market data and contains no trade logic.
  • StartProtection handles creation and cancellation of protective orders.
