The trading mistakes that blow accounts

Trading isn’t only about a better strategy. The emotional traps, risk mistakes and bad habits that lose most accounts, what each looks like, and what to do instead.

Most traders spend their time looking for a better strategy. But most accounts aren’t lost to a bad strategy. They’re lost to what traders do around it: chasing a move, revenge trading after a loss, oversizing to win it back, moving a stop. What you don’t do matters just as much as what you do. A good strategy with these habits still loses money; an ordinary one without them can work.

Here are the traps, grouped into three kinds, with what each one looks like in the moment and what to do instead.

Emotional traps

The feelings that make you break rules you already know.

FOMO: chasing a move

Looks like: Price is flying without you, so you jump in late, at market, with no sweep, no CHoCH and no pullback.

Why it costs you: You buy the top or sell the bottom, with a stop that has to be huge or in the wrong place. Late entries are where most losing trades come from.

Instead: If you missed it, you missed it. Write “missed, no chase” in your journal. There is another session in a few hours.

Revenge trading

Looks like: A loss stings, so you go straight back in to “win it back”, often the other way, often bigger.

Why it costs you: You are trading your feelings, not the chart. One normal loss becomes three, and that is how a fine week becomes a bad month.

Instead: After a loss, close the chart for at least 30 minutes. The next trade must meet every rule, not “close enough”.

Chasing losses (doubling up)

Looks like: Down for the week, you double the size on the next trade so one win gets it all back.

Why it costs you: This is the gambler’s martingale. It only needs one more loss at double size to do real damage, and losing runs of 5 or more are normal.

Instead: Same risk on every trade, win or lose. A drawdown is fixed by time and good trades, never by bigger ones.

Overconfidence after a winning run

Looks like: Four wins in a row and you feel unbeatable, so you size up, loosen the rules or take setups you would normally skip.

Why it costs you: Winning runs end, usually just as you have raised your risk. Many accounts are lost straight after the best week.

Instead: Treat a winning run exactly like a losing one: same size, same rules, same checklist.

Fear: skipping or cutting good trades

Looks like: After losses you skip a valid setup, or close a winner at +1R the moment it pulls back.

Why it costs you: A 1:3 strategy needs its winners to reach 3R. Cutting them early or skipping the next one quietly removes the edge.

Instead: Size down until the money stops scaring you, then let the plan run. Set the target and walk away from the screen.

Hope: holding a loser

Looks like: Price is near your stop, so you move it, remove it or “give it a bit more room”.

Why it costs you: Your stop is your risk. Move it once and a 1R loss becomes 2R or 5R, and one bad trade wipes out a month of good ones.

Instead: The stop goes in when you enter and it only ever moves towards profit, never away.

Boredom trading

Looks like: Nothing has set up all morning, so you take something, anything, just to be in a trade.

Why it costs you: No setup means no edge. These trades are coin flips with a spread to pay.

Instead: No trade is a position. A day with no setup is a good day if you followed the rules.

Trading on tilt or when unfit

Looks like: Tired, angry, rushed, drunk, stressed about money or arguing with someone, and still clicking buttons.

Why it costs you: Your rules are only as good as the state you are in when you apply them.

Instead: If you would not drive in that state, don’t trade in it. Sit the session out.

Comparing yourself with social media

Looks like: Screenshots of huge wins make you feel behind, so you push harder to catch up.

Why it costs you: You only see the wins people choose to post. Chasing someone else’s numbers makes you break your own rules.

Instead: Compare yourself with your own journal from last month. That is the only scoreboard that matters.

Risk mistakes

The sizing and stop habits that turn a normal loss into a blown account.

Over leveraging

Looks like: Picking a lot size because it “feels right”, or using all the leverage the broker allows.

Why it costs you: At 5% a trade, ten losses in a row (which happens) takes 40% of the account. At 0.5% it takes 5%.

Instead: Risk 0.25% to 1% a trade. Decide the money first, then let the 10 pip stop set the lot size.

No stop, or a mental stop

Looks like: “I’ll close it if it gets there.” Then it gets there fast, and you freeze.

Why it costs you: News spikes and gaps go straight through mental stops. One trade without a stop can end an account.

Instead: Every trade has a hard stop in the platform before you leave the order screen.

Adding to a losing trade

Looks like: Price goes against you, so you add more at a “better price”.

Why it costs you: You are increasing your risk on the idea that is already wrong. Averaging down is how small losses become huge ones.

Instead: Only add on a pullback in a trade that is already working, in the day’s direction, with the stop at entry or better.

Ignoring your daily loss limit

Looks like: Two losses, then a third and fourth trade to “end the day green”.

Why it costs you: The worst days in most journals are the days with the most trades.

Instead: Two losses in a day and you are done. Write it down and come back tomorrow.

Gambling on red folder news

Looks like: Entering just before CPI, NFP or a rate decision because “it will fly”.

Why it costs you: News spikes ignore liquidity, widen spreads and slip stops. It is a coin flip with extra costs.

Instead: Stand aside 30 minutes either side of high impact GBP and USD news.

Forcing it on a prop challenge

Looks like: Days left on the challenge and short of the target, so you size up to get there.

Why it costs you: That is exactly how most challenges are failed: one oversized trade hits the daily loss limit.

Instead: Pick firms with no time limit where you can, and keep the same risk on the last day as on the first.

Bad habits and bad strategy

The everyday shortcuts that slowly undo a good plan.

Taking half a setup

Looks like: The sweep is there but no CHoCH yet, or the CHoCH is there but no pullback. “Close enough.”

Why it costs you: The edge is in the full sequence. Half a setup is a different strategy with no track record.

Instead: Use the pre trade checklist. Anything unticked means no trade.

Strategy hopping

Looks like: Three losses in a row, so you drop the strategy for a new indicator or a YouTube setup.

Why it costs you: Every strategy has losing runs. Switching at every one means you only ever experience the losing part.

Instead: Judge a strategy over at least 50 trades taken exactly by the rules, not over a bad week.

Mixing in bits of other strategies

Looks like: Adding an RSI here, a trend line there, a tip from a group chat, until the rules are different every day.

Why it costs you: You can’t measure or improve rules that keep changing. Bits of bad strategy dilute a good one.

Instead: One set of written rules. Test any change in Backtests first, one change at a time.

Overtrading

Looks like: Trading every session, every pair, every small move.

Why it costs you: More trades means more spread, more mistakes and more tiredness, not more profit.

Instead: One direction a day, at most a couple of planned entries, on one pair you know well.

Blindly copying other people’s trades

Looks like: Taking a trade because someone else did, without knowing why.

Why it costs you: You can’t manage a trade you don’t understand, and you learn nothing you can repeat on your own.

Instead: Make your own call before you look at anyone else’s. The founder’s trades are there to learn from, not to follow.

Not journalling

Looks like: Trades taken and forgotten. Same mistakes, month after month.

Why it costs you: Without a record you can’t see your patterns, so you can’t fix them.

Instead: Journal every trade and every skipped setup, with a screenshot and how you felt.

Trading without a plan for the day

Looks like: Opening the chart at 08:30 with no Asia box marked and no idea what you are waiting for.

Why it costs you: Without a plan you react to every candle, and that is where FOMO and boredom trades come from.

Instead: Before 08:00: mark the Asia box, check the news, write “if the high goes I look to sell, if the low goes I look to buy”.

How to actually stop doing them

• Write the rules down, including the “don’ts”: two losses and done, same risk every trade, stop never moves away.
• Use a checklist before every trade. Anything unticked means no trade.
• Journal the mistakes, not just the trades. Tag each trade with any trap you fell into. After a month you’ll see exactly what each habit costs you in R. Our trading journal guide shows how.
• Size down when emotions are high. After a losing run or a big win, halve your risk until you feel neutral again.
