# How To Calculate Forex Volume Of A Trade

Posted By :

## Forex Volume Calculation

When placing a trade using the Metatrader 4 platform, as well as specifying my Stop Loss, I also need to specify the Volume which will determine how much I am risking (and how much I will make if the market goes my way).  In this example I want to be long (Buy) the EUR JPY:

Entry Price: 112.97 (which I put in “Opening Price”)

Stop: 112.58 (which I put in “Closing Price”)

Volume: 0.05

With this volume, it is stating my risk (“Profit”) is \$19.20 which is what I want (\$4000 account, I want to risk 0.5% which is \$20).

If the risk is not what I want it to be, I simply change the volume and re-calculate until I know the volume I want.

## Calculating Volume For Non-Forex Markets

But I have an issue.

When I want to trade other markets (Gold, the Dow, Caterpillar, etc), how do I calculate the volume as I haven’t been able to find an equivalent online calculator to the Forex calculator I use above.

In Metatrader 4 you can right click a market in the Market Watch window and select “Specification” ### Deutsche Bank Trade Volume Example

This will give you all the specs for the market, e.g. for Deutsche Bank bank Contract Size * Tick Value * Tick Risk * Volume Step
1 * 0.01 * 6 * 1

Entry: 13.30
Stop: 13.51
Tick Size = 0.01, hence risking 21 ticks

I want to risk \$20, so calculation is

Volume = Risk Amount / (Contract Size * Tick Value * Tick Risk * Volume Step)
Volume = 20 / (1 * 0.01 * 21 * 1) = 95 (rounded)

### Gold Volume Example Entry: 1332.25
Stop: 1323.33
Tick Size = 0.01 hence risking 892 ticks

Volume = Risk Amount / (Contract Size * Tick Value * Tick Risk * Volume Step)
= 20 / (100 * 1 * 892 * 0.01) = 0.02 (rounded).

Also note the “Minimal Volume” = 0.01 so I am good trading with a volume of 0.02.

### Mind The Bid / Offer Spread

Please note that the above examples do not factor in the bid / offer spread which for the major markets is small hence is makes very little difference to my volume calculation. But where the bid / offer spread is significant, simply add it to the size of your stop (i.e. if you have a 20 pip stop and bid / offer spread is 10 pips, you are effectively risking 30 pips so your volume calculation should reflect this).
