Why do i get Margin Exceeds even though I seem to have enough margin?

Hi, I am  completely new to this so let me apologize if the question is silly.

I am trying to make the following trade.

USDINR MAR 68.50 CE

  • PRICE

    ₹0.11

  • TRIGGER PRICE

    ₹0.07

  • QUANTITY

    1000

  • ORDER TYPE

    SL

  • PRODUCT / VALIDITY

    NRML /

STATUS

REJECTED

STATUS MESSAGE

RMS:Margin Exceeds,Required:110000.00, Available:8968.95 for entity across exchange across segment across product

So why is the margin required 1000 times the cost of the trade which is (11p x 1000 = 110 Rs)?
