Infinite Loop Problem

[elitetradernyc]

Hey guys I am using an indicator AutoTrendH, it works fine with no references to the variables below but when I run my backtest, this line of code appears to be stuck in an inifinite loop. Any idea how to avoid this? If i comment the line, it does not occur. The indiactor is in the indicator library on this forum.

Print("AutoTrendLine: " + AutoTrendH(true, true, 1500).TrendPrice + " Up or Down: " + AutoTrendH(true, true, 1500).Direction + " Close: " + Close[0]);

Thanks,
EliteTraderNYC

How much data are you backtesting this on? So if you load the default shared indicator on the same data amount, would it take this long to load up as well?

Hi, what is the default shared indicator?

[NinjaTrader_Bertrand]

The one that you've downloaded from the sharing section here...

I was backtesting on 1 years data minute. Yes it was the one directly from the forum, no modifications.

[NinjaTrader_Bertrand]

Right, but if you applied the indicator directly without any calls from your strategy, how would it perform?

[elitetradernyc]

It works okay without the statement: Print("AutoTrendLine: " + AutoTrendH(true, false, 1500).TrendPrice + " Up or Down: " + AutoTrendH(true, false, 1500).Direction + " Close: " + Close[0]); even though I add it to the chart. When I end the backtest, it says object reference not set.

I see, I would suggest contacting the original author then to inquire about a potentially upgraded version available and if he had seen the same return accessing those exposed values. I think he also added a strategy demo working with the same indicator?

Hello ElitetraderNYC:
The problem is that you are using a Strength parameter setting of 1500. AutoTrendH uses the built-in Ninja Swing indicator internally. This indicator has a limitation of a lookback of 250 bars. If you open your output window (icon located at top of your chart) you should see this error thrown with values above 250.
The Strength parameter is a lookback setting that determines the strength of the trend, typically it would be considerably less then 1500 (maybe between 5-30 bars)
Hope this helps

Hello EliteTrader
The line is just a debugging Print statement when the indicator was being drawn. It should have been removed prior to posting. Commenting it out or deleting it is fine.
