I have searched for the life cycle of NinjaScript for NT7 but I wasn't able to find it. I have a strategy that I don't want to over trade, so I will be enabling my strategy and it will activate an ATMStrategy. For now what I have

private bool tradeAgain = true;

protected override void OnBarUpdate()
{

if(tradeAgain)
{

// programming logic

}

tradeAgain = false;

}

After the trade, whether its profit or loss, I want to be able to make the variable tradeAgain = true.

I am wondering if I disable the strategy, and then enable it again, will variable tradeAgain be true or false?

If you want to trade or not trade based on if your last trade was a profit or not you will need something like this.



// In order to run this, you have to call the method below to check and make sure there is at least one trade in the
// collection otherwise it will just error out.

if (Performance.RealtimeTrades.Count > 1)
{

// get variables to hold information about the last trade

Trade lastTrade = Performance.RealtimeTrades[Performance.RealtimeTrades.Count - 1];
double lastProfit = lastTrade.ProfitCurrency * lastTrade.Quantity;

// Run condition to check if the last trade was profitable or not
if(lastProfit > 0)
{
// last trade was a winner do something
}

if (lastProfit <0)
{
// last trade was a loser do something
}


}


In terms of disabling or enabling your strategy, you can do something inside of the code blocks I have provided. There are a number of easy way to tell it to trade or not trade.

Thanks. Will this be for each script or will it take into account all the trades? I need it to run separately on each script. And if lastprofit > 0, simple return will suffice?

The way the code works it is only looking at the last trade.
The variable lastTrade is indexed to -1 which means it will always look at the last trade. You can add a new variable called twotradesago and index it to -2, and do threetradesago with -3, etc. Each of these would be a different trade variable and you would have to extract the p&l stats the same way.

VariableName.ProfitCurrency for example. But I think if all you are looking for is the last trade then go with the -1 index and you have it.

Thank you very much!
