EA based on only three indicators. Open / sell positions with predetermined S/L and T/P

Hello Developers!

I want to have an EA to trade for MQL4 that will take in consideration three main indicators:

1-      Oscillator  - Build in indicator

2-      Trend – An Exponential moving average - Build in indicator

3-      Volume – it´s a  Build in indicator

The EA shall execute the following:

·         once it closed above/below a reference line / value (indicator 3) and once the criteria for the remaining two indicators match for the first time after it crossed on the same closed candle open a Buy/Sell position (Upon is above or below) with a predefined S/L and T/P that is a multiplier of ATR.

·         It will be required to check the Spread before the position in order to launch a pending Buy/Sell Order with Ask Price = (Ask – spread)/ Bid Price = (Bid + spread) with a limited validity.

·         If it doesn´t match on one direction shall simply continue to try to see if it matches on the new direction.

·         It cannot open a new position until the first opened position is closed and until the line of the indicator 3 crosses the reference line again.

It shall have few external inputs for the indicators, but there are remaining inputs that must be allowed to modify at the start of the code (including the ATR), therefore, I need and want the full source code of the EA.

More info, will be provided before the beginning of the job.

Thank you!
