Modify working time of EA

Very simple job.

 I have an EA that opens positions everytime on 9AM at london open.

At 9AM it opens a buystop en selllimit based on the high and the low of the past 24hours. so based on the high and the low of the last day. 

I am able to modifie 9AM into 8AM or something else, so that's allready a good thing.

But i would like to be able to modify those 24 hours working zone. 

Example i would like to open it a buystop and selllimit based on the past 8 hours (asia session only).

Please add extra function into the EA between the setting where i can select the number of hours where the EA needs to look for the high & the lows.

The EA also always makes a RED rectangle so i can see the working zone clearly. 

When i would modify the working hours in the settings, also modifie that RED recangle zone, so i can see the working zone clearly on my screen. 

Extra thing:

Add extra function in the settings: hedging: true/false.

When true, a hedge order will open position in the opposite direction only when SL/TSL hits, witht the same TP/SL/TSL of the initial entry)
