How much free cash, you leave when trading futures?

To reduce chances of a maintenance margin call?

 

My margin/equity ratio is usually 15-17%.

 

My cash position is always many times my maintenance margin. Sometimes up to a factor of 10.

 

I'd assume that would depend on your brokers margin requirements. Ie: Interactive Brokers is around $1200 for 1 YM contract but Infinity Brokerage is only around $500.

Or you could just convert it all to gold coins
