Question About NinjaScript Function

[GLFX005]

Hello staff,

Is there a way in the NinjaScript to prevent a strategy from entering a new trade if the prior one was closed with a profit?

Let's say that trade A is active and running a profit when it suddenly receives a signal to exit and reverse position into trade B; but instead ignores trade B and waits for the signal that would reverse trade B and enter into trade C.

I'm looking forward to your reply, thank you in advance for your time.

Hello GLFX005,

Thanks for your post.

"Is there a way in the NinjaScript to prevent a strategy from entering a new trade if the prior one was closed with a profit?" Yes, you would need to check the last trades PNL and if positive then use that to set a bool variable that you create and then use as part of the entry conditions to prevent the entry of the new trade.

Please see the help guide link here: https://ninjatrader.com/support/help...collection.htm The first example shows how to get the the PNL of the last trade that you can check to see if profitable.

Hello Paul,

I tried the following method but it doesn't allow me to even enable the strategy;

protected override void OnBarUpdate()
{
bool xembel = false;

if (lastTrade.ProfitPercent > 1)
{
xembel = true;
}

// Buy
if ((Close[0] > Close[1])
&& (Close[1] > Close[2])
&& xembel == false)
{
EnterLong(Convert.ToInt32(DefaultQuantity), @"L");
}

// Sell
if ((Close[0] < Close[1])
&& (Close[1] < Close[2])
&& xembel == false)
{
EnterShort(Convert.ToInt32(DefaultQuantity), @"S");
}
}

Are you able to find any mistakes I'm making?

Thank you for your time, I appreciate it a lot

Hello GLFX005,

Thanks for your reply.

Please review the example in the help guide again. This is what you would be missing

if (SystemPerformance.AllTrades.Count > 1)
{
Trade lastTrade = SystemPerformance.AllTrades[SystemPerformance.AllTrades.Count - 1];
if (lastTrade.ProfitPercent > 1)
{
xembel = true;
}
}

Note, you may want to add the print statement from the help guide example so you can see how the percent is expressed. Print("The last trade profit is " + lastTrade.ProfitPercent);
