Bars since entry as an exit condition

[dafonseca]

What if I want to exit a position if a condition apply after X bars since entry..

if (Medians[0][0] < SMA (BarsArray[0],SMACycle)[0] && XXX)
{
ExitLong();
}

what would be XXX?

[NinjaTrader_Lance]

You would use
BarsSinceEntry() > X

The other overloads that might be of use when dealing with signal names or multi series scripts can be found here:

If I insert on my strategy:
if (BarsSinceEntry() >= 60 )
{
ExitLong();
}

The strategy does not generate any trades.. If I take this part out, it generates several trades,,

Any clue?

[NinjaTrader_Lance]

Unfortunately that bit of code alone is not enough to determine why it would not generate trades.

When you look at the start of the chart, are you seeing a trade that's entered but never closed out? Do you have more than 60 bars on the chart?

Try adding print statements or drawing tools to figure out how your code is being processed: http://www.ninjatrader.com/support/f...ead.php?t=3418

Attached in the code..
if you take the '/*' out you will see that any trade will be generate.

/*if ((Medians[1][0] < SMA (BarsArray[1],SMACycle)[0]) && BarsSinceEntry() > 30)
{
ExitShort();
}*/

If you go to tools -> output window you'll see an error message when running the script

**NT** Error on calling 'OnBarUpdate' method for strategy 'sp500testingBarssinceEntry/080a137567be4da6922a79c3efa40da3': You must use the overload that has a 'BarsInProgress' parameter when calling the BarsSinceEntry() method in the context of a multi-time frame and instrument strategy.

When using a multi series script you will need to identify the correct BIP.

BarsSinceEntry(int barsInProgressIndex, string signalName, int entriesAgo)

Let me know if I can further assist.

Nice to know!
but what would be signalName? (I read about it on guide but I did not understand what is it?)


BarsSinceEntry(int barsInProgressIndex, string signalName, int entriesAgo)

Thank you!

[NinjaTrader_Lance]

Looking at your script you're using this to enter

EnterLong(0,positionTaken,priorClosePrice.ToString());

The String you have on the end is the signal name

This will need to match. Because you're dynamically changing your signal name each new order you would need to either store store the signal name to a variable or hard code the string signal name.

Just one more question:
The strategy generates all orders in inst [0], should I have to use bas=rsInProgressIndex =0???

BarsSinceEntry(int barsInProgressIndex, string signalName, int entriesAgo)

[NinjaTrader_Lance]

Yes you'll want to use BarsInProgressIndex 0 any time you're not using a multi series script as the primary series will always be 0.
