Level II Data

[keepsimple]

Hi,
i am trying to use the drawtext method to plot the calculated level II data on the chart.
i have some print statements which print the information correctly in the output window.
so what i am trying, is to plot the same data on the chart from within the onmarketdepth method, the code compiles, but when i insert the indicator in the chart, i get one of the following error messages.
BarIndex needs to be greater/equal 0.
or
drawtext start barsago out of valid range 0 through -1 was 0.
how to get the data from onmarketdepth on the chart?

Hello keepsimple,

Thanks for your post.

In the OnBarUpdate section do you have code to return if a certain number of bars have not been produced? For example if (CurrentBar < 10) return; If so does the number of bars relate to the number of bars in the drawtext?

If that does not resolve the issue, please post the section of code you are using to draw text with.

Hi Paul,
thanks for quick reply.
The indicator, is plotting on real time only, and there are way more bars, than set in the drawtext statement. when the indicator is inserted, it draws the desired text once and then i get the error message.
code looks like the following, it is located in onmarketdepth
DrawText("ASK" + askRows[idx].Price, "" + askRows[idx].Volume, 0, askRows[idx].Price, Color.Black);
dont know why it does not work.

Hello,

The drawText statement appear valid and assume you have tested (printed) the IDX values.

Please post a sample code file so I can test on my end or if you prefer you can send it to PlatFormSupport[at]Ninjatrader[dot]com atten: Paul with reference to this thread.
