Frequently Asked Questions
How much to risk per trade?
Most pros risk 0.5-2% per trade. Over 2% leads to rapid drawdowns — risking 5% and losing 10 in a row would cut the account by ~40%.
How is position size calculated?
Size = (Balance x Risk%) / (Entry - Stop). With a $10k account risking 1% ($100) and $5 per-share risk, you would buy 20 shares ($100/$5).
What is a good R:R?
Minimum 1:2 is recommended — target distance >= 2x stop distance. With 1:2 R:R you only need a 34% win rate to break even.
