Dealers Trade v7.51 RIVOT (C#)

Summary

Dealers Trade v7.51 is a martingale-style grid strategy that was originally delivered as the MetaTrader 4 expert advisor Dealers_Trade_v_7.51_RIVOT.mq4. The port keeps the original idea of trading away from a pivot-based directional bias, scaling into the dominant side whenever price retraces by a configurable pip distance. The StockSharp implementation uses high-level strategy helpers to subscribe to candles, calculate the pivot zones, and manage position sizing, risk, and exits.

Trading Logic

  1. Pivot framework

    • The strategy builds two reference prices on every finished candle:
      • Classic pivot (P) = (previous high + previous low + previous close + current open) / 4.
      • Floating pivot (FLP) = (current high + current low + current close) / 3.
    • A gap in pips between P and FLP must be greater than or equal to GapThreshold to enable trading for the current bar.

  2. Directional bias

    • When the candle close is above both pivots and the gap filter is satisfied, the bias switches to long.
    • When the candle close is below both pivots with the gap confirmed, the bias switches to short.
    • The bias remains in force until the position series is fully closed or the opposite condition appears after the series ends.

  3. Scaling entries

    • Only one series of trades can be active at a time.
    • The first entry follows the bias immediately.
    • Additional entries are opened only when price retraces against the active bias by at least PipDistance pips from the most recent fill, emulating the original martingale averaging.
    • Each new order multiplies the previous size by VolumeMultiplier but never exceeds MaxVolume.
    • The number of stacked entries is limited by MaxTrades.

  4. Risk controls

    • A hard stop-loss at StopLoss pips from the volume-weighted average entry closes the entire series.
    • A fixed take-profit at TakeProfit pips locks in gains once price reverts in favor.
    • When enabled, the trailing-stop dynamically locks profits by stepping closer to price every time it moves further than TrailingStop pips beyond the average entry.

  5. Reset conditions

    • Any full exit (stop-loss, take-profit, trailing-stop or manual position flattening) resets the martingale counters and removes the directional bias.

Parameters

Parameter Default Description
Volume 1 Base order size for the first entry.
MaxTrades 5 Maximum number of averaged entries per series.
PipDistance 4 Minimum adverse movement (in pips) required before adding a new position.
TakeProfit 15 Distance from the volume-weighted average entry to close the entire grid in profit.
StopLoss 90 Distance from the average entry that triggers a protective exit.
TrailingStop 15 Trailing-stop offset applied once price travels in favor; set to zero to disable trailing.
VolumeMultiplier 1.5 Factor used to increase the order size for each subsequent entry.
MaxVolume 5 Cap for the single-order volume after applying the multiplier.
GapThreshold 7 Minimum gap (in pips) between the classic and floating pivots required to activate the bias.
CandleType 15-minute time-frame candles Candle type used for calculations and decision making.

All parameters are configured through StrategyParam<T> so they can be optimized inside StockSharp Designer or Strategy Runner.

Usage Notes

  • The strategy relies on candle data only; no direct tick-level bid/ask stream is required. Ensure that your data provider can deliver the selected CandleType.
  • Because StockSharp aggregates positions by default, the implementation maintains an internal volume-weighted average to emulate the MT4 grid book. If partial fills occur, the built-in position accounting keeps the values consistent.
  • Chart rendering adds two horizontal lines (Pivot and FloatingPivot) to the chart area when it is available.
  • There is no automatic reverse trading; the system waits for the ongoing series to finish before accepting a bias flip.

Differences from the MQL Version

  • The original script drew multiple labels and comments on the MT4 chart. The port keeps only functional trading logic and replaces the visuals with StockSharp chart lines.
  • Account-protection features based on total open orders, manual magic number filtering, and symbol-specific pip value tables are not required in StockSharp and were omitted.
  • Order closure at exact tick prices (Ask == tp) in the MetaTrader code is approximated with price comparisons on candle closes.
  • Trade management is implemented with market orders (BuyMarket/SellMarket) instead of MT4 ticket loops. Trailing stops and exits happen on candle updates.

Best Practices

  • Always test the strategy in paper trading or historical simulations with realistic spread/commission models before going live.
  • Consider lowering VolumeMultiplier or MaxTrades on highly volatile instruments to control drawdown.
  • For intraday products, adjust CandleType to match the data granularity of the original setup (the default is 15 minutes, but the EA was frequently used on M15 and H1).
