News Pending Orders Strategy

This strategy places a pair of pending stop orders around the current price and manages them as the market evolves. It is intended for trading during news releases where sharp moves are expected.

How it works

  • When flat, the strategy places:
    • A buy stop order at Ask + Step.
    • A sell stop order at Bid - Step.
  • Pending orders are repriced every TimeModify seconds if the market moved by at least StepTrail.
  • When an order is executed, the opposite pending order is cancelled.
  • A protective stop-loss and optional take-profit are created based on entry price.
  • The stop-loss can be moved to break-even after a defined profit and then trailed as price moves further.

The strategy operates on Level1 data and does not rely on any indicators.

Parameters

Parameter Default Description
Step 10 Distance in ticks for placing pending stop orders.
StopLoss 10 Initial stop-loss in ticks.
TakeProfit 50 Take-profit in ticks (0 disables).
TrailingStop 10 Trailing stop distance in ticks.
TrailingStart 0 Profit in ticks before trailing is activated.
StepTrail 2 Minimum change in stop price (in ticks) to send a new stop order.
BreakEven false Move stop to entry after reaching MinProfitBreakEven.
MinProfitBreakEven 0 Profit in ticks required to move stop to break-even.
TimeModify 30 Seconds between pending order repricing attempts.

Notes

  • Orders are managed using the high-level StockSharp API.
  • The strategy cancels protective orders when the position is closed.
  • Only the C# version is provided; no Python implementation is included.
