An Expert Advisor based on EMA's and Donchian Channels is required.

For a buy I want the EA to recognise that I am above the 100 EMA on the 1hr timeframe, above the 100 EMA on the 15m timeframe and also above the 100 EMA on the 5m timeframe. I would then like to open up a buy order when price breaks above the 5m 20 period donchian channel. Then for the stop loss I would like to trail the stop loss by 2 pips below the low of the 5m 20 period donchian channel.

For a sell I want the EA to recognise that I am below the 100 EMA on the 1hr timeframe, below the 100 EMA on the 15m timeframe and also below the 100 EMA on the 5m timeframe. I would then like to open up a sell order when price breaks below the 5m 20 period donchian channel. Then for the stop loss I would like to trail the stop loss by 2 pips above the high of the 5m 20 period donchian channel.

I would also like an option to change the parameters, and also be able to change the risk placed per trade. I only want 1 trade opened per asset at a time, I would not like multiple positions to be open on the same asset at the same time.

Ideally, I would not want the stop loss to trail until I am at 1-1 risk to reward. So if I risk £100 I would not want the EA to trail the stop loss until I am £100 in profit. This part is not essential though, and can be left out if it is too difficult.

Looking forward to hearing a response.

Thanks
