Hi @hareshhm,
Your overall stop loss (SL) will be 25% of the difference between the premiums of the buy legs and sell legs.
In the above case, the premium for the buy leg is 227.95 * 45 = 10257.57, and the premium for the sell leg is 120.1 * 15 = 1801.5.
Therefore, the overall stop loss is 25% of (10257.57 - 1801.5) = 2114.
