Options trading information

The two image i have attached for example
nifty 7000 ce
What is the premium for this, and buy order it’s say quantity 75 what if i type 1 instead of 75 that will means 1 lot of 75?
1933.85 is for one share or for 75? I’m getting very confused.

hello trader,

Futures contracts are dealt in lot sizes.

75 here represents the 75 units in 1 lot.

You can buy a min of 1 lot which = 75 units.

The price 1933.85 is the cost of 1 unit.

The total premium for 1 lot = total units in a lot * cost of 1 unit.

In this case = 75 * 1933.85 = 145038.75.

The concepts will clear up once you start trading with it.

Thanks your answer clears all confusion , and for buying 1 lot i need Rs 145038.75 right?

Yes, you got it right.

Simples, isn’t it ?

Yeah seems so. Thanks again

Last thing i want to ask if i buy one lot rs 145038.75 if the risk is limited how much money I’ll lose

Dear friend all profit and loss are depend on premium. If premium is greater then you paid than it profit, if less it loss. It more the diffrence more the profit and loss.
All depend on Delta, Vega, theata, rho etc. To check them you can check options calculator
