Could I place a trade for 100$ without having margin call?

Hi

I don't want to leave too much money in the broker account but just almost the required amount for the trade.
Let say I want to place a trade where my risk is 100$ and the potential reward is 200$.
The question is: "could I place the trade for 100$ without having margin call if my account balance is 200$?".
My broker is OANDA and there is a leverage variable between 10% and 100%.

Thanks

You need to keep margin money and this depends on your leverage. (approximate margin is illustrated below)
For example : you trade a lot of 0.10 (10,000)
if leverage of 1:50 then margin will be $200,
if leverage is 1:100 then margin will be $100
if leverage is 1:200 then margin will be $50
if leverage is 1:500 then margin will be $20

For example : you trade a lot of 0.01 (1,000)
if leverage of 1:50 then margin will be $20,
if leverage is 1:100 then margin will be $10
if leverage is 1:200 then margin will be $5
if leverage is 1:500 then margin will be $2

Thanks for your reply.
I placed a trade as per image:
Units: 16324
Risk 100£
Reward 202.19£
Leverage: 100%
Trade value: 8835.55£ (I didn't understand how Oanda calculate this value????)
Margin used: 88.36£
Account balance: 248.22£

Let see how it goes.
Bye
