Why does my indicator change bars on tick chart

[td_910]

Hi,

I have indicator, that does extensive calculations with CalculateOnBarClose = false;
It seems to change bars on the chart!?

I tested this using market replay for today's ES ETH session. Left chart is 2000 tick chart without indicator, right chart with indicator.

After hitting F5 both charts look the same again.

I included tick counter in chart to show, that no ticks were dropped.

There is also a very odd thing I observed, during the 1st bar I marked on right chart, price made a new intra-bar high (no tail on top), pulled back a tick and had no tail on top as well !!!

Thanks for any help

think I found error

never experienced this before, forgot to check for barsAgo to be greater than 0

This was one of the conditions causing this

                    if (EBDBO_barsback<5 && Low[EBDBO_barsback]>SB_Low) EBDBO_barsback = -1;

changed to:

                    if (EBDBO_barsback>0 &&  EBDBO_barsback<5 && Low[EBDBO_barsback]>SB_Low)  EBDBO_barsback = -1;

I do a lot of programming, but never experienced this odd behavior before, is there a explanation for it? Is it only happening with tick charts? I programmed indicators for time based charts before only.

Working perfect now. http://screencast.com/t/ATXmqUtHj
