Scalping is the most demanding form of trading. You enter and exit in minutes or seconds, executing dozens of trades per day. Without iron-clad risk rules, scalping becomes a slow-motion account blowup. These 12 rules keep you alive.
The 12 Rules
1. Maximum 0.5 percent risked on each trade. At 20 trades per day, total daily risk is 10 percent. That is aggressive - consider 0.25 percent.
2. Daily loss limit of 3 percent. Stop trading when hit. No exceptions, no revenge trades.
3. Minimum 1:1 risk-reward on every entry. Scalpers need 1.5:1 or better to survive transaction costs.
4. Never widen a stop. If price hits your stop, you are wrong. Move on.
5. Calculate lot size from stop distance. Risk equals stop pips times pip value. Not gut feel.
6. Trade maximum 2 pairs simultaneously. Split attention equals missed exits.
7. Trade only during London and New York overlap. Spreads are tightest and volume highest.
8. Exit before major news. Spread spikes destroy scalpers. Flat 5 minutes before NFP.
9. Maximum 3 losses per hour. Take a 15-minute break after.
10. Track every trade in a journal. Your biggest leak is hiding from yourself.
11. Review weekly, not nightly. Sample size matters for evaluation.
12. Cut size in half after any daily loss. Your judgment is impaired when down.
The Math Behind the Rules
The numbers exist because ruin is asymmetric. Ten straight losses at 0.5 percent risk cost about 4.9 percent of capital; the same streak at 2 percent costs over 18 percent. Recovery arithmetic is worse: a 10 percent drawdown needs an 11 percent gain to break even, 20 percent needs 25, and 50 percent needs a double. The equity curve forgives small errors and compounds large ones against you, which is why rule 1 caps the damage before any trade idea gets a vote. Compound the daily limit across a week and the ceiling is clear: five full 3 percent days cost about 14 percent of the account, a hole that takes weeks of clean trading to dig out of.
Common Failure Patterns
Every blown scalping account follows the same three steps. A trader takes three quick losses, doubles size to win the money back before the session ends, then widens the stop because the entry was clearly right. Rules 2, 9, and 12 exist precisely against that sequence. The moment you notice yourself negotiating with a rule is the moment to close the terminal. The market reopens tomorrow; a broken account does not.
A Structured Session
Put the rules into a schedule. Two sessions a day: the London open and the New York overlap, with a hard cap of ten trades total. Journal each fill during the session with entry, exit, stop distance, and one line on why. On any day the loss limit or the three-losses-per-hour rule triggers, the session ends and the notes get written while the memory is fresh. Review on the weekend scores the week, not any single day. Preset the bracket templates before the session so entry takes one click, because manual stop placement under pressure is where the rules go to die.
Execution on Ruaytrade
Ruaytrade offers costs opening at 0.2 pips across Raw+ accounts with 28ms execution. At 20 round-trip trades, transaction cost is roughly 8 pips. Your average winner needs to clear 12+ pips for profitability. Use bracket orders that auto-attach stop and target on entry.
Before going live, run the same rules on demo for two hundred trades and count the cost drag honestly. When you switch to a live Ruaytrade account, start at half the intended size for the first month. The best scalpers are not smarter - they are more disciplined. These rules automate the discipline.
