EA that Opens trades based on the Indicators Buy or Sell Signals

I need an EA that will automatically open Buy or Sell Trads based on the Indicators Signals.

The indicator needs to do the following things

Trade according to sessions:

I want to have the ability to choose the sessions ( Asian, London, American ) that i want the EA to trade, i want the option to select the hours per session.

Opening a position:

1. Open one position per session ( Asian, London, American )

2. Open one position + Re-Entry at a time All Sessions ( this means that the EA will open one position at at time, but if the position is closed, it can be opened later on in the day )

2. Open One position per day ( All sessions only once )

3. Open one position every time the Signal is given by the indicator, It will open as many positions as the indicator gived signals.

Trade Logic:

The Indicator i uses this types of alert, as soon as the alert is given either Buy or sell, the ea will immediatly open a market order ( BUY OR SELL )
