PriceTypeSupported = false has no bearing when adding an indicator to an MA

[Day Trading Fool]

Hi,

I created an indicator with PriceTypeSupported = false which has no impact when I add the indicator to an MA - I can still select price type.

Also - the indicator I am using seems to be fairly taxing on the comp's resources and about every other time I adjust the columns NT hangs up on data load/calc. I am using B22 and DTN IQFeed. If you are interested I can send you the indicator and MA template.

Thanks.

I have been messing around with this some more and realized that I am not getting the same value on the MA indicator as the chart indicator. Seems that '# of bars to look back' property has a definite influence on the result. But - with that being said, I made the property value 10000 bars and still did not receive the correct value on the MA.

I am using range 15 bars.

I have also run across this problem with a very simple indicator for the MA, something that lists the HOD - the last price, but I eventually got it figured out. I set the data series to the 5 minute and had to include at least 78 bars (6.5 hours the market is open * 60/5) for the indicator to list the correct value on the MA. I am not sure how to come up with a universal value for range bars. I would think 10000 bars would cover the vast majority of stocks.

But - that being said, the indicator is based on a several EMA's - one with a period of 300. I am not sure that any of this has relevance or how to even go about calculating the correct number of lookback bars.

Any help appreciated.

Day Trading Fool, can you please post the code you're using so we can see what's going on?

[Day Trading Fool]

Sure.

This is not the code is not for the indicator in the picture - I broke this down to a single series to try and debug it.

I am still messing around with this. It appears as though a shorter range parameter works fine. If I set the primary to 5 and the secondary to 6 and the number of bars to look back to > 300 then I get matching results on the MA.

Not sure what this means.

The value of the indicator on the MA changes significantly with # of bars to look back. I even went as far as trying 100,000 bars on the 15/22 range bar periods with no success.

[Day Trading Fool]

I re-did the conditionals if you want to play around with the results and brick size.

Hello there, can you please explain how the values differ from the values you're expecting for using all these bars back? Are you sure the indicator you're using doesn't "accumulate" error over so many bars?

[Day Trading Fool]

Yes - in fact, I have no idea what the # of bars back is actually supposed to do - I assumed that since there is a 300 period EMA in the indicator that the MA needs at least 300 bars to calculate the correct value.

I am simply checking the position of one ema with respect to another. I am assigning simple integer values to the assessment. I think the setup in the picture used something like -2, -1, 0, 1, 2.

When I select a very low # of bars to look the value is way off - I get a weird value of 169.25 or something - which should be impossible (the indicator can only assign the range of values above). As I increase the # of bars the value begins to reflect the domain, I know at 50 bars I get domain values., but they do not match the chart output, e.g., the chart shows -1 and the MA shows 0 or something. As I increase the # of bars the MA value changes. At some # of bars it begins to sporadically match the chart output.

I also run into a 'not enough bars' error (can't recall the exact syntax) on the log if I select too large of a value - I do not understand that relationship either.

[NinjaTrader_Austin]

Day Trading Fool, can you also post the code for the DoubleMA referenced in your post so we can test this out?

[NinjaTrader_Bertrand]

DayTradingFool - would you mind emailing the files needed to set this up to test on our end? You can reach me at support at ninjatrader dot com - thanks

[Day Trading Fool]

Sure.

Recall - the indicator has the correct output on the chart - well, it is at least assumed that what is displayed on the primary panel is correct. I will setup up a new workspace so you can see what I am talking about.

[Day Trading Fool]

Any progress on this?

[NinjaTrader_Bertrand]

Yes, I sent you a reply yesterday already on your email, please check your inbox...

Thanks

[Day Trading Fool]

I changed the MA session to 24/7. Unfortunately, the indicator still does not match the value displayed on a chart.

[NinjaTrader_Bertrand]

Do you then load enough historical data in the MA to replicate the chart the indicator is applied to?
