Convert TradingView indicator to MT5 + add engulfing-candle strategy for a trading bot

I need an experienced MQL5 developer who is also experienced in pinescript of tradingview to:

1. Recreate my TradingView indicator in MT5 (non-repainting), with the same signals and values.

2. Build an MT5 trading bot that trades those signals with a simple price-action filter (liquidity sweep + engulfing candle during the london kill zone) and basic risk management.

Indicator concept (full tradingview code will be provided)
• The indicator compares the percentage move of the current chart symbol against a user-selected reference symbols over a lookback window.
• It then takes the difference (spread change), rescales it to a −100…+100 range over a rescaling window, optionally smooths it, and prints buy/sell signals when extreme thresholds are crossed.
• In TradingView this is signal-only (with visual labels and alerts). I want the same behavior in MT5: one indicator that plots the normalized line (or at least exposes buffers) and raises buy/sell markers at the same bars as TradingView.

Key requirements

• One MT5 Strategy/EA (.mq5) that:
– Uses the converted indicator along side sessions like Asian Session, london session and trade only when an additional price-action filter passes (see Strategy logic below).
– Implements simple inputs for risk, stops, targets,BE and trade management.

Price Action Strategy
First we use london opening compared to the asian session range to determine the bias for the day.
Once we have got the bias, we wait for asia low/high to be swept
After asia has been swept, we wait for the indicator to give a buy signal if the day bias is buy or a sell signal if the day bias is sell. 
Once the signal (which paints an amount of candles red for sell or green for buy) appears, we wait for the low/high of the painted candle to be swept
After its swepts, we enter the first engulfing candle( which can also be the candle that swepth the painted candle), the second or the third only. We can enter other engulfing candles only if the candle the engulf shares range with the sweeping candle.
