Expert Advisor based on taking trades when price moves to or touchs the 20 EMA

Looking to develop an EA that takes trades based of the price bouncing/moving away of/from the 20 moving average

It must check a specified higher time frame for the trade to be valid

set a 1-1 or 1-2 risk reward 

check for horizontal levels

be able to take a trade early on the lower time frame (definition of whats early and late in a phase can be defined)

There are these criteria above + 6 other rule/criteria's that needed to be met for the trade to be confirmed

we can discuss this at the start of the project

This may be an ongoing project as I have other strategies that I will need developing if this first one is a success

Thanks
