I'd like to call separate instances of a customer indicator I have created. But I'm not sure how to have multiple instances as more than one call to calculate access a single instance of the indicator. Please see code attachment. The output this strategy produces as follows showing the threshold setting from the previous call already in place (keep switches between 10 and 50).

18:18:16 Existing threshold: 10.0, new threshold: 50.0
18:18:16 2. Calling calculate with threshold: 50.0
18:18:16 Existing threshold: 50.0, new threshold: 10.0
18:18:16 1. Calling calculate with threshold: 10.0

Clearly my code is crap but not sure how to fix. I.e. how can I have 2 or more instances of a user indicator please? thanks.

Indicator calculations should be based only on input prices and optional input parameters.
Is there a situation where this is insufficient?

Hi, yes I agree so I havent explained my self very well. I was trying to create a strategy where I have 2 indicators and where they cross I either buy or sell. However I couldn't find a code model where you can have 2 separate instances of the same custom indicator where each instance would have its own set of parameters. When I tried to have 2 separate instances of the same indicator it didnt work as it only generated a single instance. Obviously my attempt was poor however I couldnt figure out the correct way? Does that make better sense? cheers.

Along these lines, How do I call multiple custom indicators. What is the syntax here??? It would be VERY HELPFUL in your API to give simple examples of syntax like MQL does. That would solve probably 30% of the questions here on this forum...

@CustomIndicators("E:\\Documents and Settings\\Administrator\\My Documents\\Jforex\\Indicators\\Best_Volume.jfx")
("E:\\Documents and Settings\\Administrator\\My Documents\\Jforex\\Indicators\\MDDummy.jfx")


Thanks!
