What is the difference using this indicator on forex, can it be of use? since there is no volume on forex, only ticks,

how does the indicator know if 1 tick is a sell or a buy? I am interested in delta volume but I'm not sure how much help it can provide me,

I'm only trading forex.

Did you read this indicator description? It's clearly stated there that tick volumes are used as a limited substitution for real volumes which are not available on Forex. For a detailed explanation how it works please read the blog post - Can we trade volume delta on Forex? - which has been already mentioned in the comments. Instant price change direction defines buy or sell nature of a tick.

PS. To be more precise, instant price change is only known for related indicator - VolumeDeltaM1, whereas VoumeDelta reconstructs price and volume changes from M1 timeframe.

Yes I did read it but I didn't fully understand it, and delta is still a bit confusing to me, then the question is,

what I want to detect, is if some big trader trade extremly huge lots in 1 tick, not necessarily instant price change,

I rather would like to know it before the price change, which one of the two indicators do you recommend that will pick that up best?

thanks

The delta is coming from M1 bars (for VolumeDelta) - consider them as "large ticks". Then you can analyze volumes separately during up and down movements, and accumulate them for a containing bar on a larger timeframe. Unfortunately, you can't see placed volumes on Forex beforehand. All you can see is (tick) volumes in past (including near past). Using these both indicators you can not know next move "before price change", initiated by "some big trader extremely huge lot" order. But they will show you on the history, where such traders did most likely make their trades - keep an eye on bars with arrows.

For your use case, VolumeDeltaM1 looks more interactive and accurate (in approximation of real volumes).

ok, I' thinking of getting the volumedelta, but lets say I wanted to trade futures, does it also read real volume or does it only read the ticks?

It only works with tick volumes. But are you talking about MT5? MT5 provides much more info about real volumes, so if your broker supports this you don't need such an indicator.

Hi,

Could you please enlarge the histogram bars' size at the bottom? When viewing only the delta, they are hard to see, especially on larger time frame.

Current scale = Pic.1

Desirable scale = Pic.2


Thanks a lot~

Hi, I'm afraid this is impossible due to current MetaTrader implementation. The buffers which is not displayed according to the settings of the indicator is defined as DRAW_NONE. Unfortunately, MetaTraders does not exclude such buffers from automatic scaling of the chart - I think this is a bug and can do nothing with it. Your only resort can be to set a fixed scale manually - open the indicator settings dialog, switch to Common tab and adjust Fixed minimum/Fixed maximum fields as appropriate.

Thank you very much for the explanation. Your instruction has helped alleviate the problem. Much appreciate it.

The problem has been fixed in MetaTrader 4 build 970. According to the release notes:

MQL4: DRAW_NONE buffers (no graphical constructions) now do not participate in a chart window minimum and maximum calculations in custom indicators.

So, after update you'll have no need in the suggested workaround.

Hi! I like to report a bug, I think the last update on Mt4 messed something up, 

if you change time frame with the Volumedelta plotted on the chart, it will disapear.

very annoying:)

Could you please provide more info? Symbol name, from which timeframe to which timeframe did you switch? How does it disappear - the subwindow completely or just the drawing? What about table visibility and contents after switching? Do you see some errors in logs? Does reapplying the indicator settings fix the problem?

PS Do you mean you use the build 985? It's known to be buggy (so your problem can be one of the side-effects). Please update to a hotfix when it's available and let me know if the problem persists.

It does not use real volumes. I did not test in on futures, it should work using tick volumes (if they are provided).

Is it possible to program a version of overbought/oversold Stochastic Oscillator with the parameters of VolumeDelta? Thank you sir.

I'm not sure I get you. You asked this very same question about 3 different indicators. Please, send your technical requirements to me via personal messaging.

I've developed a simple indicator calculating WPR formula on VolumeDelta. I'm going to publish it in the blogs. I'll let you know.
