MyProject #3: write EA from existing Trend Indicator

I found a trend indicator that I like and I want to trade it automatically.

The Trend Indicator gives us a value each bar.

If the bar close below this value we go short at market with stop loss x.

If the bar close above that value we go long at market with stop loss x.

The system is always in the market and reverses its position. 

x is the optimisation parameter and used for the stop loss in pips.

We have to devide between 4 digit and 5 digit brokers. 

A money management system is set on top of it. Risk is defined in a parameter: y,yy

The positionsize is adjusted in that way, that

stop loss x pips = Risk y,yy % of balance

We can decide at which tradng day of week we want to trade

Monday = true/false

Tuesday = true /false

Wednesday = true/false

Thursday = true/false

Friday = true/False 

We can also define a session 

start time

end time
