MQL5 EA: W1 Keltner Trend + H4 StochRSI Pullback + H1 Candle Confirmation

Requirements Specification

Please develop a Multi-Timeframe (MTF) Expert Advisor (EA) for MQL5. The EA will use three timeframes for its logic (W1 for trend, H4 for setup, H1 for entry).

1. Filter 1: Primary Trend (W1 Timeframe)

• The EA must first check the Keltner Channel on the W1 (Weekly) chart.

• Uptrend: Confirmed if the Keltner Channel's midband is sloping up (current midband value > previous midband value).

• Downtrend: Confirmed if the Keltner Channel's midband is sloping down (current midband value < previous midband value).

• Ranging: If the midband is flat, no new trades are taken.

2. Filter 2: Entry Setup (H4 Timeframe)

• The EA only looks for setups in the direction of the W1 trend.

• The EA will use a Stochastic of RSI indicator (Stochastic applied to RSI data).

• Buy Setup: If W1 Trend is UP, the EA waits for the H4 StochRSI Main Line to cross below the Oversold_Level (e.g., 20). This arms the buy trigger.

• Sell Setup: If W1 Trend is DOWN, the EA waits for the H4 StochRSI Main Line to cross above the Overbought_Level (e.g., 80). This arms the sell trigger.

3. Filter 3: Entry Execution (H1 Timeframe)

• This filter provides the final confirmation for the trade after the H4 setup is armed.

• Execute BUY Trade:

  1. The W1 Trend must be UP.

  2. The H4 StochRSI must be "armed" (have recently been in the oversold zone).

  3. The EA will then monitor H1 candles.

  4. A BUY trade is executed on the open of the next candle after an H1 candle closes green (Close > Open) AND its Close is higher than the previous H1 candle's Close.

• Execute SELL Trade:

  1. The W1 Trend must be DOWN.

  2. The H4 StochRSI must be "armed" (have recently been in the overbought zone).

  3. The EA will then monitor H1 candles.

  4. A SELL trade is executed on the open of the next candle after an H1 candle closes red (Close < Open) AND its Close is lower than the previous H1 candle's Close.

4. Trade Management & Exits:

• One Trade at a Time: Only one open trade allowed per pair.

• Stop Loss (SL): Must have user-selectable options:

  1. Fixed_Pips : A fixed pip value.

  2. ATR_Based : Based on the H4 ATR_Period and ATR_Multiplier .

  3. Keltner_Band : Place SL at the opposite H4 Keltner Channel band.

• Take Profit (TP): Must have user-selectable options:

  1. Fixed_Pips : A fixed pip value.

  2. Risk_Reward_Ratio : A multiplier based on the SL (e.g., 2.0 for 1:2 R:R).

  3. Keltner_Band : Place TP at the opposite H4 Keltner Channel band.
