Vortex Indicator MMRec Duplex Strategy

Overview

  • Converted from the MetaTrader 5 expert Exp_VortexIndicator_MMRec_Duplex.mq5 (MQL ID 23180).
  • Maintains two independent Vortex indicator streams: one dedicated to long trades and one to short trades. Each stream has its own timeframe, length, and bar shift so that bullish and bearish logic can be tuned separately.
  • Replicates the "MMRec" money-management recovery module from the original EA. The strategy tracks the latest trade results per direction and temporarily switches to a reduced order size after a configurable number of losses.

Signal Logic

  1. Subscribe to the configured candle type for each stream and calculate the Vortex indicator (VI+ and VI-).
  2. Long entries: when the previous bar had VI+ below or equal to VI- and the current bar closes with VI+ above VI- (bullish crossover). Entries are allowed only if AllowLongEntries is enabled.
  3. Long exits: when VI- rises above VI+ on the evaluated bar, provided that AllowLongExits is enabled.
  4. Short entries: when the previous bar had VI+ above or equal to VI- and the current bar closes with VI+ below VI- (bearish crossover), controlled by AllowShortEntries.
  5. Short exits: when VI+ climbs back above VI- on the evaluated bar, controlled by AllowShortExits.
  6. Each direction keeps its own stop-loss and take-profit levels measured in price steps. Hitting either level immediately closes the position and registers the result for the recovery counters.

Money-Management Recovery

  • The original EA inspects a sliding window of past trades to decide whether the next order should use the normal or reduced volume. This port mirrors the same behaviour.
  • For long trades the queue stores up to LongTotalTrigger most recent PnL results. If at least LongLossTrigger of them are losing trades, the next long entry uses LongSmallMoneyManagement; otherwise it uses LongMoneyManagement.
  • Short trades repeat the same logic with ShortTotalTrigger, ShortLossTrigger, ShortSmallMoneyManagement, and ShortMoneyManagement.
  • When the trigger values are zero the queues are cleared and the base volume is always used.

Margin Modes

MarginModeOption describes how the money-management value is turned into an executable volume:

  • FreeMargin (0): treat the value as a fraction of capital (approximation of the original "free margin" mode).
  • Balance (1): identical to FreeMargin in this port; uses the current portfolio value.
  • LossFreeMargin (2): risk a capital fraction using the configured stop-loss distance. Falls back to price-based sizing if the stop distance is zero.
  • LossBalance (3): same as LossFreeMargin in this implementation.
  • Lot (4): interpret the value directly as order volume.

All calculated sizes are normalised using the instrument's volume step as well as minimum and maximum volume constraints.

Parameters

Parameter Default Description
LongCandleType H4 Timeframe used to feed the long-side Vortex indicator.
ShortCandleType H4 Timeframe used to feed the short-side Vortex indicator.
LongLength 14 Period of the Vortex indicator for long signals.
ShortLength 14 Period of the Vortex indicator for short signals.
LongSignalBar 1 Closed-bar offset evaluated for long crossovers (0 = latest closed bar).
ShortSignalBar 1 Closed-bar offset evaluated for short crossovers.
AllowLongEntries true Enable long entries when the bullish crossover appears.
AllowLongExits true Enable closing long positions when VI- dominates VI+.
AllowShortEntries true Enable short entries when the bearish crossover appears.
AllowShortExits true Enable closing short positions when VI+ dominates VI-.
LongTotalTrigger 5 Number of recent long trades inspected by the recovery counter.
LongLossTrigger 3 Losing long trades required before switching to the reduced long volume.
LongMoneyManagement 0.1 Base money-management value for long trades.
LongSmallMoneyManagement 0.01 Reduced money-management value after a long losing streak.
LongMarginMode Lot Interpretation of the long money-management value (see modes above).
LongStopLossSteps 1000 Protective distance below the long entry expressed in price steps.
LongTakeProfitSteps 2000 Take-profit distance above the long entry expressed in price steps.
LongSlippageSteps 10 Informational slippage allowance for long orders (not used for sizing).
ShortTotalTrigger 5 Number of recent short trades inspected by the recovery counter.
ShortLossTrigger 3 Losing short trades required before switching to the reduced short volume.
ShortMoneyManagement 0.1 Base money-management value for short trades.
ShortSmallMoneyManagement 0.01 Reduced money-management value after a short losing streak.
ShortMarginMode Lot Interpretation of the short money-management value.
ShortStopLossSteps 1000 Protective distance above the short entry expressed in price steps.
ShortTakeProfitSteps 2000 Take-profit distance below the short entry expressed in price steps.
ShortSlippageSteps 10 Informational slippage allowance for short orders.

Implementation Notes

  • Built entirely on the StockSharp high-level API. Candle subscriptions drive the Vortex indicators through Bind, which delivers finished bars before any decision is made.
  • The trade-recovery logic stores per-direction profit series in queues and mirrors the MetaTrader BuyTradeMMRecounterS / SellTradeMMRecounterS functions.
  • Stop-loss and take-profit levels are recalculated in price units (instrument price step × configured steps) and enforced on every incoming candle.
  • Order volumes are normalised via the security's VolumeStep, MinVolume, and MaxVolume constraints to avoid invalid submissions.
  • Slippage parameters are preserved for documentation purposes but are not used directly by the StockSharp order handlers.
