Size a LYTE trade from its stop
Hypurr Desk asks where your stop goes and how much of your account you are willing to lose there, then works out the size. An example at 17.483, from when this page was built:
- Account
- $1,000.00
- Risk
- 1% = $10.00
- Stop
- 2% below entry, at 17.133
- Size
- 27.14 LYTE ($474.68)
- Loss at the stop, fees included
- $10.00
- Leverage
- 10× isolated, $47.47 margin
The stop sets the loss, not the leverage: leverage only decides how much margin the position ties up. Move the stop and the size follows, so a wider stop means a smaller position and the same loss. The stop is placed on the exchange with the entry. How risk sizing works.
