Whale RSI and SMA

This Expert Advisor is a reversal-style system that combines a 50-centered RSI extreme filter with a 200 SMA proximity rule. It evaluates signals only on a new bar of the selected timeframe and uses closed-bar data (shift=1) to reduce noise and avoid “in-bar” flicker.

How the Strategy Works

On every new candle (for InpTF ), the EA follows this logic:

1. Compute RSI thresholds around 50
   A single parameter creates both buy/sell levels:

   • BuyLevel = 50 − InpRSIThresholdDist

   • SellLevel = 50 + InpRSIThresholdDist
     Example: Dist = 20 → BuyLevel = 30, SellLevel = 70

2. Require price to be near the 200 SMA
   The distance between the last closed candle’s close and the SMA must be within a maximum range:

   • Distance (points) = abs(close1 − sma1) / _Point

   • Must be ≤ InpMaxDistPoints
     If the distance is also ≤ InpAggroDistPoints, the trade is considered Aggressive and uses a tighter SL buffer.

3. Optional confirmation filters

   • EMA Trend Filter (optional)
     If enabled:

     • Longs require close1 > ema1

     • Shorts require close1 < ema1

   • Volume Filter (optional)
     If enabled, the last closed bar’s tick volume must be at least:

     • avg_tick_volume(lookback) * InpVolMultiplier

4. One-position rule (per symbol + magic)
   If there is already an open position on the same symbol with the same InpMagic , the EA will not open a new one.

5. Stop/Target calculation + broker rule normalization

   • SL is set using last closed bar’s high/low plus a buffer.

   • TP is either Risk/Reward based or Bollinger Middle based (with fallback).

   • SL/TP are then adjusted to comply with StopsLevel / FreezeLevel / Spread plus InpExtraStopBufferPts .

Entry Rules

BUY (Long) Conditions

A Buy is triggered when all are true:

• RSI(shift=1) < BuyLevel

• abs(close1 − sma1) in points ≤ InpMaxDistPoints

• If EMA filter is enabled: close1 > ema1

Stop-Loss (SL)

• SL = low1 − SL_Buffer(points)

Take-Profit (TP)

• If InpUseRRTP = true :

  • risk = entry − SL

  • TP = entry + risk * InpRR

• Else (BB middle mode):

  • TP = BB_Middle

  • If BB_Middle is not valid (≤ entry), it falls back to RR TP.

SELL (Short) Conditions

A Sell is triggered when all are true:

• RSI(shift=1) > SellLevel

• close1 < sma1 (explicit in the code)

• (sma1 − close1) in points ≤ InpMaxDistPoints

• If EMA filter is enabled: close1 < ema1

Stop-Loss (SL)

• SL = high1 + SL_Buffer(points)

Take-Profit (TP)

• If InpUseRRTP = true :

  • risk = SL − entry

  • TP = entry − risk * InpRR

• Else (BB middle mode):

  • TP = BB_Middle

  • If BB_Middle is not valid (≥ entry), it falls back to RR TP.

Input Parameters (All Variables Explained)

Timeframe / Core Indicators

• InpTF: Signal timeframe used for all calculations (default: M5).

• InpRSIPeriod: RSI period (default: 14).

• InpSMAPeriod: SMA period (default: 200).

RSI Threshold Logic (Centered at 50)

• InpRSIThresholdDist: Distance from 50 to define extremes.

  • BuyLevel = 50 − dist

  • SellLevel = 50 + dist
    Notes: The EA clamps the value into [0, 50] .

SMA Distance + Aggressive vs Cautious SL Buffer

• InpMaxDistPoints: Maximum allowed distance from SMA (points).

• InpAggroDistPoints: If distance is within this tighter band, trade is Aggressive.

• InpSLBufferAggroPts: SL buffer (points) used in Aggressive mode.

• InpSLBufferCautPts: SL buffer (points) used in Cautious mode.

Optional EMA Trend Filter

• InpUseEMAFilter: Enable/disable EMA trend filter.

• InpEMAPeriod: EMA period (default: 50).

Optional Volume Filter (Tick Volume)

• InpUseVolumeFilter: Enable/disable tick volume confirmation.

• InpVolLookback: Bars used to compute average tick volume (closed bars).

• InpVolMultiplier: Required multiplier vs average (e.g., 1.2 = 20% above average).

Take-Profit Mode

• InpUseRRTP:

  • true → Risk/Reward TP

  • false → Bollinger middle TP (fallback to RR if invalid)

• InpRR: Risk/Reward ratio (default: 2.0).

• InpBBPeriod: Bollinger Bands period (default: 20).

• InpBBDeviation: Bollinger deviation (default: 2.0).

Trading / Execution / Safety

• InpLots: Requested lot size (normalized to symbol min/max/step).

• InpSlippagePoints: Max slippage (points).

• InpMagic: Magic number to track EA positions.

• InpExtraStopBufferPts: Extra safety buffer (points) added to broker minimum stop distance.
  The EA effectively enforces:
  min_stop_distance = max(StopsLevel, FreezeLevel) + Spread(points) + InpExtraStopBufferPts

Notable Operational Behavior

• Runs only once per new bar on InpTF (no tick-by-tick entries).

• Uses closed-bar signals ( shift=1 ) for RSI/MA/candle values.

• One open position at a time per symbol and InpMagic .

• Broker-rule compliant stops: SL/TP are adjusted to meet minimum distances; if not possible, the trade is skipped.

• Trade comments label entries as Aggro or Caut depending on SMA distance.
