Almost every blown trading account fails for one of a small number of repeatable reasons. Strategy rarely gets the blame it's given — most beginners lose money to behavior, not analysis.
Mistake 1: Risking Too Much Per Trade
Beginners frequently risk 5%, 10%, even 20% of their account on a single trade because the dollar amount "feels small." A string of four losses at 10% risk each cuts an account by roughly a third. At 1% risk, the same losing streak barely registers.
Do instead: Fix risk-per-trade at 0.5%–1% of current balance, recalculated every trade.
Mistake 2: Trading Without a Stop-Loss
No stop-loss means no predetermined point where you admit the trade idea was wrong, turning a small, defined loss into an undefined, growing one.
Do instead: Set a stop-loss at the moment you enter, based on where the setup is actually invalidated.
Mistake 3: Revenge Trading After a Loss
A loss triggers an urge to immediately "win it back," often with a larger position than the previous trade.
Do instead: After two consecutive losses, step away for a set period before taking another trade.
Mistake 4: Overtrading
Taking trades outside your tested setup just to "stay active" dilutes a real edge with random noise.
Do instead: Define your setup clearly enough that "no trade today" is an acceptable outcome.
Mistake 5: Chasing the Market After Missing an Entry
Jumping in late at a worse price with a wider stop-loss converts a good setup into a poor risk-reward trade.
Do instead: If you miss your entry, let the trade go.
Mistake 6: Ignoring Correlated Risk
Multiple trades that all depend on the same underlying move multiply risk without the trader realizing it.
Do instead: Check total exposure across all open positions before adding a new one.
Mistake 7: Skipping the Demo-to-Live Transition Discipline
Jumping to a live account at full intended size immediately changes behavior due to real psychological pressure.
Do instead: Transition to live trading at reduced size first.

Every mistake on this list is a behavioral failure, not an analytical one.
