How to use tick volume and real volume in forex - General

amando 2020.04.22 17:07 #11

A single tick does t have an volume, a volume can only apper over a period of time

Alain Verleyen :
There is no problem. Most brokers don't provide trade volume information for Forex symbols.

You are confusing tick volume and real volume. Tick volume is broadcast for all Forex symbols. It’s for some reason that I can’t get the tick volume - there is only one CopyTickVolume function "/

Methods SYMBOL_VOLUME , SymbolInfoTick , do not work. Please do not confuse tick volume and real volume.

Also you can't get the latest price with SymbolInfoTick().

Do you know the problem with SymbolInfoTick () is eventual with a short term solution?

Should we find another way to get the latest price and volume for each tick?

YOU are confusing tick volume and real volume.

SYMBOL_VOLUME is about REAL volume, not tick volume.

MqlTick volume and volume_real are about REAL VOLUME. The tick volume of a tick is obviously 1.

Yeah, you're not going to get real volume because forex doesn't have a centralized exchange. If you want to know the real volume you will need to trade futures at a FCM. Other than that use tick volume like Alain has mentioned several times.

Volume[0] function returns wrong MQL5 Automatic validation always Do you know any

Thank you!

Alain - many thanks! I really rarely refer to EXCHANGE symbols. You have helped me!

Now I will show the correct code - thanks to it you can see all the volumes:

Thank you again Vladimir and Alain. You have helped me a lot!

powerbucker 2021.06.03 14:28 #19

Hi,

starting from this code, how could I do to get de volume grouped for every tick on every candle? I need an indicator that shows the buy and sell volume for every tick on a candle (showing on log, for example)

Thank you

israelhernando: starting from this code, how could I do to get de volume grouped for every tick on every candle? I need an indicator that shows the buy and sell volume for every tick on a candle (showing on log, for example)

Then read this thread again, because it answers that very question.
