I have an Expert that needs some changes

The EA works with two indicators: Hilo and trendsignal.

It can use one of them or both.

Problem 1:
When the button AutoTrading is clicked sometimes one order is put between the signals.
I want put one order only the signal change from buy to sell or sell to buy, not in between signals.

The EA will put order working with one of indicators and both.

Problem 2:
The trendsignal indicator have one parameter SSP - standard value = 9 - if used in optimization and SSP <> 9 result in 00.00 for all results. However, the indicator accept values differents of 9.

I want use these parameter in optimization and the results should be nonzero.

Problem 3:
The EA have one parameter AddPositions that put a new order in same direction - buy or sell - at each candle. I need change it to put a new order at new parameter PipStep instead MaxTradePerBar, that allow put new orders per candle.

The PipStep is distance in pips from the current price - Ask or Bid - from the last order. So, if PipStep = 30 means when price is distant 30 pips from last price order a new order in same direction will put.

Problem 4:
I need new parameter DeltLot. DeltaLot can be positive or negative to increase or decrease the lot of new order. Example:
Lot = 1.0
DeltaLot = + 0.1 increase Lot with DeltaLot and the lot of new order is equal to 1.1
Lot = 0.1

DeltaLot = - 0.01 dearease Lot with DaltaLot and the lot of new order is equal to 0.9
