Update code to allow for multiple pair trading, time and money based exits, account load limits for guranteed profitability.

I inlcuded two new time exits.
input bool closedaily = false; //Close all trades at new day
input bool close_after_X_Hours = true; //Close trade after x hours
input int X_Hours = 24; //Maximum number of hours for each trade

Implementing time based exits.

Live trading results suggest I need to upgrade the exit strategy.
Now additional time-based exit and close condition has been added to ensure consistent profit without large drawdowns.

(1) All trades now open and close within a day. That helps us to avoid swaps and also not allowing loosing trades to run.
(2) An exit condition where our entry assumptions are obviously wrong.

The EA will perform better with these changes.
