Learn How to Apply a Position Size Calculator | How to Measure a Lot Size
In this educational article, I will teach you how to apply a position size calculator and calculate a lot size for your trades depending on a desired risk.
First of all, let's briefly discuss why do you need a position size calculator.
Even though, most of the newbie traders trade with the fixed lot, the truth is that fixed lot trading is considered to be very risky.
Depending on the trading instrument, time frame and a desired stop loss, the risks from one trade to another are constantly floating. With the constant fluctuations of losses per trade, it is very complicated to control your risks and drawdowns.
A lot size calculation, however, allows you to risk the desired percentage of your capital per trade, limiting the maximum you can potentially lose.
