When you specify a strategy using 100% equity in TradersPost, the system only refers to your available cash balance. It does not automatically use your margin funds. For example, if you have a $10,000 account and an additional $10,000 in margin, a 100% equity order will use $10,000 (your cash) and not the margin.
If you want to include margin in your trades, you need to set a percentage higher than 100%. For example:
• To use 25% of your margin, set the equity to 125%. This will use all your cash plus 25% of your available margin.
• If you don’t have margin available and try to use more than 100%, the order will be rejected by the broker due to insufficient funds.
