Simple crossover strategy

[bppayne]

Hi; I hired one of the 3rd party developers listed on the NT site to write a simple EMA crossover strategy; when the fast EMA crosses above the slow EMA, it goes long, when it crosses below, it goes short. The problem is the strategy shuts down when there is more than one trade during the day. It is a EOD system. Can I have you look at it for errors? I do not want to post it on this site. I am executing through TDAmeritrade.

bppayne,

I am not sure what you mean by shutting down when there is more than one trade. Can you please elaborate?

I would recommend you try going back to the consultant that did the work for you and see if they can address the issue since it was their code.

Usually this strategy trades once during the day; occasionally it will trade 2 or 3 times; ie, if it goes long at 10, then goes short at 12, it should close out the long and enter a trade in the other direction. Thats where the problem is; I get error messages and the strategy terminates. The long position is closed, but the short does not get entered.

I have gone back to the consultant, he's re-written it 3 times total; same problems.

Let him know that for the TDA adapter, he needs to explicitly exit the long position, wait for confirmation, and then explicitly enter a short position via ExitLong and EnterShort.
