Well, now that we know how to calculate the value of 1 pip, calculate the position size that will be used in a trade is really simple.
In this article we will not discuss about how much risk in a trade, which would be the subject of another article, so the first thing to calculate is the monetary amount you are willing to lose in the transaction.
Assuming for example that the size of our trading account is 2,000 EUR and we apply a monetary management in which we risk 1.5% of the account, it is easy to determine that the maximum loss we are willing to assume in a trade is 30 EUR (2000 EUR * 1.5%).
We assume also that the position opened will have a stop loss set in advance. Therefore, as the value of 1 pip is known, then would be easy to calculate the loss in the account in case the price reaches the stop loss for each contract involved in the transaction.
Let’s see some examples:
