How do I calculate the lot size?
When choosing the lot size for your trade, you may want to consider a few factors:
- The price levels (or number of pips) you want to set your Stop/Limit
- The amount of capital you wish to risk
- The amount of Usable Margin you have available to open new trades
Based on those factors you can calculate lot size.
FXCM APPS created a 'Risk Calculator', which will help you determine a LOT size to trade based on the parameters above.
