Enter long and short orders for multiple instruments in a single strategy

[tickleboy]

Hi there. I'm having some difficultly trying to implement an idea. Basically I've added over 100 ETF Instruments in my strategy. What I'm looking to do is every 5 bars or so:

-Run calculations on all instruments in the strategy
-Buy the top 5 instruments
-Short the bottom 5 instruments

For some reason, I get long 1 instrument and short 1 instrument, but I can't get long or short the 5 instruments.

I am using the method call

IOrder order = EnterLong(key, tradeSize, entrySignal);

where:
-key is the index value in the BarsArray
-tradeSize is = 1
-entrySignal = "ETF" + key + "-" + CurrentBar

So the first one works, but in Visual Studio I can see that every method call to EnterLong after that returns null. Any ideas why?

Sigh.... so after posting I remembered I can set TraceOrders to true and then was able to see that my EntriesPerDirection was equal to 1. After setting EntryHandling to UniqueEntries, it is now working.

My apologies. Please feel free to bill me for my waste of bandwidth. :-)

No worries, great to hear it works for you now. All the best.
