Tick Charts or Constant Range Bars
well is it possible??
In generally words - it's possible. Look example on Russian article 18. Тиковый индикатор в отдельном окне
Rosh,
You look like a scientist :) I guess you are one... computer scientist.
I think I understood a little bit of that code you were trying to explain. Can you post it here and provide some English annotations? we will try to decipher the best we can.
thanks.

no rosh, i dont have a clue as to what their trying to do there, but basically just
like each bar in a minute chart is created at the end of a minute, in a tick chart,
1 bar will be created when the number of ticks you have specified is reached, nothing
is done to the price....
Yes, each bar in a every time frame chart is created at the end of a specifyed peiod.
But there is way to solve this task? for example:

thank you much Rosh, can i ask you a question? How can i modify the default Stochastic included with mt4? What I basically want to do is to change the "Price field" to be derived from ... (H+L+C+O)/4 ... how can this be achieved?
I don't know why you really need Stochastic from (H+L+C+O)/4 .

wow, thank you soo much Rosh, i looked for places to add this (HLCO)/4 but could
really understand where. thank you. The reason why i asked you about this was because
in my prior software, that was the setting that i had used. hmm Rosh, it seems
that this is simple moving average? Is it possible to create options like the default
stochastic indicator in mt4, like "Smoothed, Exponential" etc? tia
Hmm.... eating and scratching wants but a beginning ? :)

Would it be possible to write some type of indicator that plots constant tick charts or constant range bars in another window? These are different forms of charting that are not time based. For example, a 100 tick bar is formed whenever price moves 100 ticks. So on little volume, no bar is formed. A constant range bar is formed whenever price moves a set number of ticks in a range. For example, a range bar set at 20 forms whenever price fills a 20 pip range. Then the next bar is started. I was told my a Metaquotes developer that it was possible. Does anyone know how to do this? Your help is much appreciated.
