Mission Impossible Power Two Open Strategy

Overview

This strategy is a StockSharp port of the MetaTrader expert advisor “Mission Impossible Power Two Open”. It monitors the direction of the most recently completed candle and opens a new basket of trades in that direction. When price moves against the active basket, the strategy adds new averaging entries according to a fixed pip grid. The volume of each new entry grows with the floating loss of the basket, mimicking the power-based sizing rule from the original EA. Exit targets are recalculated after every fill so that the entire basket shares a single take-profit and stop-loss level.

Trading Logic

  1. Signal detection – On every finished candle the strategy compares the previous candle’s close with its open.
    • If the previous candle closed above its open, the long signal is active.
    • If it closed below the open, the short signal is active.
    • An inside bar (close equal to open) produces no new basket.
  2. Opening the first trade – If no grid is active in the signaled direction, the strategy places a market order with the BaseVolume size.
  3. Averaging grid – When a basket exists, the strategy keeps measuring the distance between the last filled price and the current close.
    • For longs a new entry is added once price falls by at least GridStepPips * PriceStep below the last fill.
    • For shorts the strategy waits until price rises by the same distance above the last fill.
    • The grid stops adding new positions after MaxTrades fills have been reached in the respective direction.
  4. Dynamic volume – Before sending each new order the strategy computes the unrealized loss of the basket, multiplies it by Power * 0.0001, and adds the result to BaseVolume. The final size is rounded to the exchange volume step, clamped between the security limits, and capped by MaxVolume.
  5. Exit management – After every fill the strategy recomputes the shared targets for the whole basket:
    • With a single position the take-profit is TakeProfitFirstPips away from the entry and the stop-loss is StopLossPips away in the opposite direction.
    • With two or more positions both levels are anchored to the volume-weighted average price of the basket, using TakeProfitNextPips for the target distance and StopLossPips for protection.
    • When price touches either the take-profit or the stop-loss all positions in that direction are closed at market.
  6. Independent baskets – Long and short grids are tracked independently. The strategy can hold both at the same time when alternating signals arrive.

Parameters

Name Type Default Description
BaseVolume decimal 0.01 Initial order size for a new basket before scaling.
MaxVolume decimal 2 Hard cap for a single market order after rounding.
Power decimal 13 Multiplier applied to the floating loss when calculating the additive volume for new entries.
StopLossPips int 400 Distance in price steps used for the shared stop-loss.
TakeProfitFirstPips int 15 Take-profit distance for the very first entry in a basket.
TakeProfitNextPips int 7 Take-profit distance for averaged baskets (two or more entries).
GridStepPips int 21 Minimum adverse move (in price steps) before another averaging entry is allowed.
MaxTrades int 16 Maximum number of grid trades per direction.
CandleType DataType TimeSpan.FromMinutes(5).TimeFrame() Candles used for signal generation and basket management.

Notes

  • Order volumes are always aligned to the instrument’s VolumeStep, restricted by the security’s MinVolume and MaxVolume whenever those limits are available from the trading board.
  • Long and short state machines are fully separated, allowing the strategy to maintain hedged baskets when market direction alternates quickly.
  • The protective levels are recalculated on every fill and rounded to the nearest PriceStep, matching the frequent take-profit modification routine performed in the MetaTrader version.
  • No indicator buffers are used; all decisions are based on raw candle data and portfolio information, just like in the source EA.
