Volume - Basic Question

[Sat]

Hi Friends, I am completely new. I am trying to get my head around Volume. I am so far given to understand that Volume is number of ticks / bar and if that is so, should'nt I expect the volume value at a particular bar on the 10 minute chart to be roughly twice the volume value for the preceding 2 bars on the 5 minute chart ? Now By preceding here, I mean 2 consecutive bars on the 5 minute chart completing at the same time as the 10 minute bar in question ?

It doesn't seem like that or I am missing something.

skt,

If you mean for example: the 03:00 M5 bar has 21 ticks, and the 03:05 M5 bar has 16 ticks ----- yes, the 03:00 M10 bar should have 37 ticks.

However, you are probably observing the problem we all encounter with the historical data sets. When the backtester encounters this kind of a problem it shows up as "Mismatched Chart Errors"

Here's a thread on this topic: 'TestGenerator: unmatched data error (volume limit 208 at 2008.06.27 19:00 exceeded)'

Cheers,

Hi,

Thanks FXTrader2008 for your help. Well, I have not yet hit any of the backtesting problems as I haven't got anything to backtest as yet. What I am failing to understand that chart on the MT screen shows these Ticks coming in and the Bar forming and then there is this time on the X-axis. I just added volume indicator to the chart and it appears as a histogram.

Now within the indicator window when I hover my mouse over the indicator window, on one of the histogram bars, it shows me the associated value for that. and that's what I was trying to compare across multiple charts for a given currency pair. If the Volume indicator has a value of 30 for the bar completed at 19:30 PM on an 15 minute chart, this value of 30 should ideally be traceable back Volume Indicator values for 3 consecutive bars on the 5 minute chart, the last of which finishes at 19:30 ? However, I am failing to identify any such correlation.

Any insights are greatly appreciated !!!

regards

The volume for a higher timeframe bar should be the same as the sum of the lower timeframe bars.

If it is not, you are probably reading it wrong.

But, I'll take a quick look, too.
