How to calculate margin

[backtester831]

Hello, I am looking for the formula to calculate margin requirement.

For example I am trading ES and have an account balance of 10,000. With 10k, I should be able to place an ATM limit order with at least 15 contracts and the ATM has a stop loss of 8 ticks. However if the ATM has reverse on stop enabled, then the stop loss part of the order will fail saying not enough margin requirement.

How is margin calculated with reverse at stop ATMs, so that I know what the maximum number of contracts I can trade at any given balance.

Hello backtester831,

Margin is different for each brokerage.

Basically the is the amount you must have in the account for each order in case that order becomes a loss.

Each brokerages calculation will be different.

You will need to contact your broker and ask what the margin is per order or per contract, depending on how that broker calculates margin.
