Convert Trading View Pine Script to MT5 EA

I am a complete rookie, so apologies in advance.

I have a Pine Script that i need converting to MT5 that i intend to use with the MT2 autotrader.

Once converted I would like the below amendment if possible.

• Currently buy/sell signals a generated regardless of trend direction. I would like it changed so it only produces the buy/sell signal to match the trend direction. EG Trendline going up - generate the buy signals but not sell signals. Trendline going down  - generate sell signals not buy signals.
