Number of elements in data series

gg80108,

Set on every single bar. Take it one step at a time. I suggest you work with regular DataSeries and see how it works. When you do not set a value, the DataSeries will autopopulate with the close price so a zero is not coming from auto population. It is coming from either a Set or a Reset.

you got the code, don,t see where the problem is you talk about.. Think the auto populate is a 0 and not the close.

I have simplified your code and it is very clear why you receive zeroes. This is why I asked you to Print the values of the calculations before each set. It is very clear from the first screenshot that the values you are receiving come from a calculated zero as the math makes it zero. You are subtracting the current PnL total from the PnL stored for the prior session. As you start a new session you have not made any trades yet so the current PnL is still the same as the stored one from yesterday. This means you get zero. You will continue to get zero until you successfully make a trade for the new session.

If I totally comment out the set statement and the reset, the array fills with 0's..

gg80108,

Please take a look at the reference I just posted in my previous post. Disregard auto fill. It is evident now that you receive zeroes from not having any trades on the new session. You will notice that you only get these zeroes as you switch to a new session and have not completed any new trades yet.

I experimented with your sampleCustomDataSeries,, I commented out the SET and printed the results . Just isnt the close of the bar but just random and if you round it off it becomes 0..

/* Take note that the method for setting the value to be plotted is the same as for setting a value
to a DataSeries object. The difference here is that the custom DataSeries object is not plotted while
this "AvgR" is plotted.

In this case we are plotting the Simple Moving Average of the intermediate calculation step stored in our
DataSeries object. */

// AvgR.Set(SMA(myDataSeries, Period)[0]);
Print ("myDataSeries value: "+ myDataSeries[0] + " bar # " +Bars.BarsSinceSession);

gg80108,

In my previous post I stated to disregard that thought process. It does not apply in this situation and is actually for plot DataSeries and not custom DataSeries.
