Porting 6.5 indicator to 7.0 -- problem/question

[MikeGutmann]

I am attempting to port a 6.5 indicator to 7.0. I exported the 6.5 source and imported it into 7.0. It compiles under 7.0. When I open the Indicators dialog, I get the following message in the Output window -- and this is BEFORE the indicator is applied:

Failed to call method 'Initialize' for indicator 'MyIndicator': 'BarsinProgress property can't be accessed from within 'Initialize' method.

However, I don't see the BarsinProgress property accessed in the MyIndicator Initialize code.

MyIndicator worked fine under 6.5. I reviewed the 6.5 to 7.0 migration notes, but can't seem to find the problem.

Thanks for any help with this!

Would you care to post your Initialize() code?

Here is the code. It appears one can no longer reference Bars in the Initialize method??

CalculateOnBarClose = false;

// Attach a market depth event handler (if connected providers does not support depth, you
// will not get any events)
if (Bars != null && Bars.MarketData != null)
{
marketDepth = Bars.MarketData.Connection.MarketDepthStreams[Bars.Instrument];
if (marketDepth != null)
marketDepth.MarketDepthItem += new MarketDepthItemEventHandler(OnMarketDepth);
}

}

That is pretty much it. No references to Bars allowed in Initialize().

Mr. Koganam,

With your help I was able to get my code working.

Thank you!
