Figure out how many shares to trade based on your risk — not a guess.
Here's the math: multiply your account size by your risk percentage to get the dollar amount you're willing to lose (Amount at risk). Then find the gap between your entry price and stop price — that's how much you'd lose per share if you're wrong (Risk per share). Divide the first number by the second, and that's how many shares to buy.
Enter your entry, stop, and target to see the ratio.
Here's the math: find the gap between your entry price and stop price — that's your risk per share. Find the gap between your entry price and target price — that's your reward per share. Divide reward by risk to get your ratio. A ratio of 1:3 means you stand to make $3 for every $1 you're risking.
