Hello,

I wanted to check with you,

This is a different indicator than the prior one that was uploaded. I imported this item and it is plotting, was there a question for this new indicator? I tried the chart settings as previously discussed and moved the chart to the start and it is still plotting.

Otherwise the answer for the first indicator is in post #14, I am not sure on the math you are using but when printing the values I see that it is not producing a number but infinity instead.

You can use Print() statements to determine this, if the new indicator is having a similar problem you can locate that problem by printing the values to ensure they are valid.

I look forward to being of further assistance.

[futurenets]

yes it plots and also throws an error when scrolling fully to left.

I use debugview but you can use print to see this.

sorry but I've run out of time so cut out everything to make it easier to solve.

I think the problem lies within

curPeriod = Math.Min(CurrentBars[1], SMAPeriod); ???

removing this removes the error

Hello,

Can you please provide a working script with what you are printing?

I do not see errors when trying to print curPeriod, I am not sure what you are printing.

I look forward to being of further assistance.

[futurenets]

ok thanks Jesse

I'll take another look when I have more time.

[futurenets]

thanks again for help.

initialization problem fixed and working.

can I ask what order are Bar objects processed e.g.

BarsInProgress == 1

then

BarsInProgress == 0

i.e. higher to lower?

Neither and both. As with all event-based programming, it is the event (in this case, a tick arrival) that is processed. The tick is queried for which BarSeries generated it, then the relevant code is run based on that.

when I add the attached DailyWMA to a daily chart and compare it with a WMA the DailyWMA is a day behind.

This is what I want but I don't understand why it's happening?

Thanks again.

ok but if 2 bar objects exist for same symbol will not the ticks be from the same source?

Yes, if CalculateOnBarClose is false. in which case the code will be run in the order that it is written, because there is, ipso facto, no branching involved.

sorry don't understand?

[koganam]

sorry don't understand?

I gave you a reference. It seems clear enough to me. If you do not understand what the reference explains, I am unable to help any further. My apologies.

Code will always run in the order that it is written, so that is all that gates the code. Yes, even in so-called parallel processing systems, that run on anything other than a cluster, code will run serially once the event that triggers the code arrives. Events arrive in any order, but the code that handles the event will always run serially, as written. In the case of NinjaTrader handling ticks from the same instrument, the reference clearly explains that NT caches the event, to save processing resources. That is how NT internally manages to handle the same tick as belonging to different BarSeries, when it so does.
