Had incorrect calculation in recent update. Have fixed this now
The calculator will now provide a gross R:R calculator if there is no commission input (left at 0)
The calculator will provide a net R:R if commission is included, and net risk will be auto calculated based on the entry price.
Your commission amount is dependent on your entry price, it is a rough estimation and is only accurate if entry and exit price are identical. Outside of this the R:R calculator is a rough estimation.
