define your opening range
The opening range is the high and low from 9:30 to 10:00 AM ET. Use that range as your breakout trigger. Only trade breakouts above the high or below the low. This filters out noise. Stick to this time window every day.
set a fixed stop loss
Your stop loss must be based on the opening range itself. Place it one tick above the range low for long trades, one tick below for shorts. Use a 2x ATR stop if the range is too tight. Never move your stop during the trade.
compare prop firm stop rules
Prop firms have different drawdown rules. You must adapt your ORB stop to their limits. Here is a comparison of how each firm handles stops.
position sizing for 1% risk
Risk only 1% of your account per ORB trade. For a $50,000 account, that is $500. Calculate position size using your stop loss distance. If your stop is $1.00 away, buy 500 shares. Do not round up. This keeps you safe through multiple losses.
scale out at 1:1 risk-reward
Take half your position off at a 1:1 risk-reward. Let the rest run with a trailing stop. This locks in profits quickly. Many traders miss this step. Do not hold for a home run every time.
