Moving average cross automated ea required

I require an ea bot to automatically open and close trades that will work for both backtesting and in live account. The trade will open on the cross of the 5 ema and the 200 ema. Stop loss will be the 50 ema and the trade will close on the cross off the 5 ema and the 50 ema. It will need to be able to run on all times frames. Lot size will be 1% of account balance. Multiple trade can be open at the same time. Magic number to also be imputted. Thank you in advance
