Improvement and adding functionality to an exisitng EA (or developing new one)

Hi,

i have an EA that is able top open positions and close positions when a horizontal line with the same color in the chart is triggered. Also lot size, stop loss and take profit could be set.

It should be a positionmanagement implemented. Actually a fix lotsize could be set. The new EA should be able to calculate the lotsize based on

1) Input of the Risk in € (account currency), this input should be added. If lotsize is 0 then the risk in € is taken into account.

2) With the distance of the OrderBuyOpenLine (opens a long position) and the BuyLineColor (which closes ALL long positions) the EA should calculate the lotsize, saame for a short scenario with OrderSellOpenLine and SellLineColor

3) The actual win / loss, position size and the actual risk should be shown on the BuyLineColor or SellLineColor

4) All lines could be moved, so of course the win/loss and the other numbers must change depending on the level of the line.

5) It must be possible to add positions and that the numbers for win/loss, risk and positionsize will reflect it.

6) The input for stop loss and take profit will stay, setting to 0 means no stop loss and no take profit

If you have already implented a smiliar solution, you can use your code. EA code will be shared after acceptance.
