Compound and Parital close function

I added the ROUND() instruction to make sure there’s only 1 decimal place.

I also added MinLots to set a minimum number of lots to be traded (but I suggest that it be at least 2, or that the minimun lots to exit is allowed to be half that number, i.e. if you set a max 1 lotsize, then the broker must allow exiting 0.5 lots) and MinExit to exit partial poisitions.

Equity = Capital + StrategyProfit

Lot2Close = max(MinExit,round(Amount/2,1)) //amount of contract/lot/shares quantity to close when breakeven occurs
