Hi all... I'm new to ninjatrader and I thought I had an understanding of how MTF should work after reading the NT7. Apparently not. My basic attempt at this generates "index was outside the bounds of the array" error.

Here's a sample of the code:

 

Code

protected override void Initialize() { Overlay = false; Add(PeriodType.Minute, 3); // 3 min time frame stored at index[1] ?? double the3minClose = Closes[1][0]; Print(the3minClose); double the3minOpen = Opens[1][0]; Print(the3minOpen); }

Any suggestions here?


(Sorry this should have been posted in NinjaTrader Programming but I don't seem to be able to move it now)

Not even close, to be honest. Please repost in the appropriate thread and I am sure someone will help you:

Want your NinjaTrader indicator created, free? Hey guys, I thought many of you would enjoy and benefit from this thread. My intention is to have each poster reply and describe in as much detail as possible an indicator they want created for NinjaTrader. The programmers on the forum (there are many), …

Thanks, srgtroy. That's a neat offer from Futures.io

I don't want or need it created for me though. Having something specific to create is what helps motivate me to learn the language.

I already have the indicator fully coded & working on another platform, but I intend to take advantage of some of the more useful features of NinjaTrader (e.g. autotrading, optimization) that the other platform is lacking.

Have you read the whole "NinjaScript" section of the NT7 Help Guide, specifically? That's the first order of business. You may also want to watch this:

@sam028 Where does this thread belong?

@Jayswiss, you can't access to bars values in Initialize(), this is what generates your error.
Check the genuine SampleMultiTimeFrame strategy, it's a good example, and the NT7 help (NinjaScript > Educational Resources > Tips > Multi-Time Frame & Instruments).

Thanks! Yes, I've since realized some of that doesn't belong in initialize section.

Thanks for the tip, I'll check the SampleMultiTimeFrame strategy.
