Hi

I want to implement call ratio back spread for sun PHARMA july by selling 470 Ce (36.1) and buying 490 Pe(2*8.25),so net credit to account becomes 19.6.And the max loss in this case

Spread -19.6=0.4.

Are the calculations ok?

As per the strategy

Sell.one lot of ITM AND BUY TWO LOTS OF OTM ,WHICH IN THIS CASE IS 470 AND 490!

Can u please correct where I am going wrong ?

Both should be calls ce

Both Are Calls .

You mentioned PE 490

Typing error…

So is the above calculation correct ?

In Call Ratio Backspread both options should belong to same Expiry, you are selling ITM CE of July Expiry and buying OTM CE of June Expiry (as per your price quoted).
