EMA Engulfing Strategy Coding

I need a Pine Script strategy for TradingView that catches both bullish and bearish engulfing patterns, but only when they line up with the prevailing 50-EMA bias. Once in a trade the script should immediately place a fixed, user-adjustable take-profit and stop-loss, then plot both the entry and the eventual exit directly on the chart so I can run native TradingView back-tests without extra tweaking. What matters most to me is clean, reliable code written by someone who already has solid experience building and debugging TradingView strategies. The finished file must compile in the current Pine Script v5, feature clear comments, and expose the following inputs in the Settings panel: • 50-EMA length (default 50) • Take-profit distance (in ticks, %, or ATR—your call, just document it) • Stop-loss distance (same unit as TP) I should be able to turn on or off position reversal, choose long-only or short-only, and see performance metrics in the Strategy Tester out of the box. If you can deliver a script that meets those points and is easy for me to tweak later, drop me a message outlining similar EMA or candlestick strategies you have coded before and roughly how long delivery will take.
