Inverted Martingale

[Karelgp7]

Can some one please help me figure out how to build a strategy that sum my position size after each won and go back to 1 if I lost.
When the first transaction reaches the Take profit line, the following transaction opens with an additional contract automatically, but if that transaction end up being negative all resets back to the initial 1 contract.

Example:
Open 1 contract (if won) open the second with 2 contracts ( if won ) open the third with 3 contracts ( if lost) go back to 1 contract for the following transaction.
(1-2-3-4-5-6-7.....) in this sequence, not doubling.

Hello Karelgp7,

This thread will remain open who would like to create this logic or the script as a convenience to you.

I am happy to assist you if you would like to create this script.

To know if the last trade is profit or loss use the SystemPerformance collection.

For example:
if (SystemPerformance.AllTrades[SystemPerformance.AllTrades.Count - 1].ProfitCurrency > 0)
{
// trade was profitable
}
else if (SystemPerformance.AllTrades[SystemPerformance.AllTrades.Count - 1].ProfitCurrency < 0)
{
// trade was a loss
}

You can increment an integer to increase the quantity size and reset this to 0 with other criteria.
