How many option contracts should I buy?

Divide the dollars you are willing to lose by the loss per contract at your stop. Example: $500 risk, $2.00 premium, −40% stop = $0.80 × 100 = $80 per contract, so 6 contracts. The planner does this for you and caps it at your account cash.

What is a good risk/reward ratio?

Many day traders want at least 1.5: you aim to make 1.5x what you risk. Below that, you need a high win rate to come out ahead. The planner flags any plan under 1.5.

How is a stop on the underlying converted to the option price?

The planner re-prices the option at your level with Black-Scholes, using the contract’s implied volatility and the time left, anchored to the real premium. It is an estimate; fills and spreads can differ.

What is the expected move?

The move the options market is pricing by expiry, read from the at-the-money straddle (or implied volatility). If your target is far beyond it, the trade needs an unusually big day.

Are the quotes live?

No. Quotes are free, indicative and delayed at least 15 minutes. Always check your broker before trading. This is an educational tool, not financial advice.
