If volume data is useful, use it !!
If you don't know how and where to get volume data, don't say volume data is useless.
The problem is that many people use volume data from market makers which are free. Or perhaps they get delayed data!
It might not be true volume data but just number of transactions.
Be careful of free thing because if you get garbage in, you get garbage out.
Use volume data from exchanges like CME, ICE, Eurex.... You have to pay for those data.
eg for ICE, datafee is around US$120 / mth for the charting software, plus another few tens of dollars to be paid to the broker.
If you are serious about trading, you have to pay for those overheads.
pay for quality data and you might get quality result.
After you have paid for the datafee and if you find volume data is useless, then your comment is valid.
