How this is calculated
Buying power left after this trade equals your total buying power minus this trade's dollar cost.
If you set aside a reserve, that amount is subtracted again to show what's actually available to deploy on another trade.
This tool works off buying power figures you enter yourself. It does not pull live data from your broker and does not account for margin requirement changes, day-trading buying power rules, or overnight maintenance requirements, which can differ from your intraday buying power.
If this trade costs more than your available buying power, you cannot place it as entered without additional funds, a smaller size, or margin your broker actually approves.
Risk & liability disclaimer: This calculator restates numbers you enter and performs basic subtraction. It is not financial advice and does not reflect your broker's live account data, margin requirements, or day-trading buying power rules, which can change intraday. Trading involves risk of loss. Trading Habits is not a broker-dealer, registered investment adviser, or tax professional, and is not affiliated with any broker, exchange, or data provider. Always verify your actual buying power directly with your broker before placing a trade. You could lose some or all of the capital you trade with.
