Specification

Hi, I am looking for a developer to convert a TV strategy into a Mt4 or Mt5 EA. The strategy is based on the EMA and the CVD volume indicator. I dont have the Mt4 or Mt5 version of these indicators. Copy the code below and place it in your TV to see the strategy. Other features:

Stop loss - Option to either use pips of my choosing or close on opposite signal appears. 

Take profit -  Option to either use pips of my choosing or close on opposite signal appears. 

EMA Filter - Must have the option to turn off and on and choose the EMA length 

Time Filter 

Trailing Stop - Can be based on pips or any other idea you may have 

Recovery - Martingale - Allow me to choose the lot size it will increase by. It will only kick in if the previous entry or entries close in a loss. It must stop or reset 

Add to winning trade - For example, a buy trade is taken and its in profit, sometimes price pulls back with 2 or more red candles, after this, a green candle must engulf any of the red candles. Once this happens additional buy entries must be taken. Allow me to choose the lot size. 

How It Takes Buy and Sell Entries:

  • Buy Entry Example:

    1. The price candle closes higher than it opened (green candle).
    2. The CVD indicator shows positive net buying (teal candle).
    3. The price is above the EMA, indicating an uptrend.
    4. The price has not crossed above the EMA more than once, and fewer than two buy signals have been generated since the last EMA crossover.
    5. All conditions are met, so the strategy enters a long position.
  • Sell Entry Example:

    1. The price candle closes lower than it opened (red candle).
    2. The CVD indicator shows negative net selling (red candle).
    3. The price is below the EMA, indicating a downtrend.
    4. The price has not crossed below the EMA more than once, and fewer than two sell signals have been generated since the last EMA crossover.
    5. All conditions are met, so the strategy enters a short position.

Summary:

This strategy combines the Cumulative Volume Delta, price action, and an EMA filter to identify trading opportunities aligned with the prevailing trend. The entry limit logic helps avoid overtrading by restricting the number of entries after an EMA crossover, while the option to enable or disable the EMA filter provides flexibility in strategy application. This approach aims to capitalize on strong, confirmed market movements while minimizing false signals.
