What am I doing wrong here?

[chancee90046]

Hello, I'm trying to get the IBPlugin working with just a basic strategy I'm testing it out with in Tradestation but I'm obviously doing something wrong. I can tell an order is being sent but it seems to be instantly cancelled and then Tradestation crashes and I have to restart. It seems to be getting caught in some kind of loop.

I have copied most of the code from the demo example and replaced some of my own code to test out a market BUY and SELL. Any help here would be much appreciated. I would classify myself as a beginner to intermediate in easy language. Thank you -James

Here is the code:

Where does it crash ?
What TradeStation version. Is it 64 bit TS or 32 bit TS ?
Thank you

[board_admin]

I checked out your code.
I am not so familar with EasyLanguage, but it seems that the CONNECT part has called with each tick,
which should not be a problem but causes unnecessary load.

Just call Connect and the conid mapping once. The Plugin will keep connection.
Find attached corrected script.

Make sure, the symbol ES is mapped to a valid not expired contract.
Since you did not INIT with a specific configuration, use the default database in Admin Tool for mapping.

Thanks for responding.... so I'm using Tradestation 10. I used your corrected code but it's still doing the same thing. As soon as I run the strategy I see an order flash in the API tab in TWS for just a millisecond and then it disappears. It keeps doing that about every few seconds. During which the cursor is just spinning over tradestation and I can't click on anything. It's frozen. I have to basically just shutdown computer and restart.

So I've been experimenting around with it and I've found that when I change the symbol to EURUSD, with the CONID you use in the demo, the orders go through, but they fire off repeated orders every second. Within a minute I had about thirty buy orders filled. Obviously it's a Demo account so no big deal.... but your IBPlugin Demo strategy with Eurusd works properly.... to all I can think is something is wrong with the code or symbol, not sure? Any help will be appreciated. Thanks.

[board_admin]

Hello Sir,
when you call a Plugin function, it is executed once.
So, if a function is fired multiple times, check your script code.

When the EUR.USD symbol works, but yours not, then your symbol is not mapped.
In this case, use the Admin Panel to map the symbol for your configuration (which is most likely "default").

Or get the conid of your ES contract and use this directly.

The example of IBPlugin executes all once, because it is within the "Initialized " condition.
Your code is outside the "Initialized" condition and get's executed which each tick.

So the fault is not with IBPlugin or the sample, it is your code.

This forum does not discusses EasyLanguage or any Script Language, just the IBPlugin functions.
You need of course to be familar with the script language in use.
