Need Modification in this EMA based EA

Problem 1: Now it opens another order when I open Mt4 again.

Need to edit:

1. It will open one trade per currency pair. If I open MT4...... it will not automatically open another order.

Problem 2: When I close (take stoploss manually) buy/sell........it creates another order of the same type.

Need to Edit: It will not open same order if profit is taken. It will wait for the opposite oder.

Problem 3: When I set this EA into the chart first time......it automatically opens an order.

Need to wait: When it is attached first time. it Will wait till the opposite signal comes. For example: I attach this EA and there is a buy condition..... it will open a Sell when sell condition is fulfilled.

another Edit: There must be option to choose timeframe to where i decide to use that EA with different magic number. For example, I will run this in H1, H4, M15 in same currency pair with different magic numbers.
