None of these need a bad setup. A good one, run badly, gets there by lunch.
“These aren't five separate mistakes, they're one mistake in five outfits: a rule that holds fine right up until the moment it costs something.”Jason Parker · Founder, TradeScalping.com
Every mistake below has already shown up somewhere else on this site, in the risk-management math or the psychology of tilt. This page puts all five side by side, with the specific fix for each one. Knowing a rule and holding onto it under pressure are two different skills, and the second one is the one that blows accounts up.
On someone else's account it's obvious, a foul in slow motion: bigger size right after a loss, the same setup that failed a minute ago, taken again before the sting wears off. On your own screen it doesn't look reckless. It looks like conviction, like the market owes you the last trade back and you're only here to collect.
The market has no idea your stop got hit twelve seconds ago. It has no idea you exist. It isn't holding the loss over your head, waiting to hand it back the moment you double the size.
The fix: one size, every trade, no exceptions after a red one. That includes the one that looks too good to skip.
This is tilt with a specific target. The psychology page goes deeper on what tilt looks like before it ever turns into a trade.
A mental stop isn't a stop. It's a suggestion you make to yourself, and suggestions move. Price gets close, the level slides twelve cents further out because this one's "about to turn." Then it slides again.
A stop you can talk yourself out of was never a stop.
An actual stop order, placed the second you're filled, doesn't negotiate. It doesn't care what you think is about to happen, and that's the entire point of using one.
Forty trades before ten in the morning isn't discipline. It's boredom wearing a trading platform. Ten quiet minutes feel like missing something, so a trade gets forced onto a chart that never asked for one.
Scalping runs on frequency, and it's easy to read that as permission: more clicks, more edge. It isn't. It's still a quality-per-trade game. Played at speed.
The fix: a daily trade cap, set before the session opens. Not adjusted at 10am because today feels different. It rarely is.
A scalp that nets three cents a share sounds fine until the round trip costs two of them. Do that forty times a day and the math stops working: spread and commission get paid first, whatever's left over is yours.
Know the break-even move before the order goes in. Entry, plus commission both ways, plus whatever the spread runs on that instrument at that hour. If the target doesn't clear that number with room to spare, it isn't a scalp. It's a fee generator with extra steps.
The exact setup that filled clean at 9:45 turns into a mess at 12:15. Same pattern, same rules, worse fills, wider spreads, and a chart that chops sideways because the volume that made the pattern work isn't there anymore.
Trade the session overlaps. Sit out the rest. The session clock on the Tools page flags the London/New York overlap on its own, so this doesn't have to be a guess.
These aren't five separate mistakes. They're one mistake in five outfits: a rule that holds fine right up until the moment it costs something. Fix that one thing and the other four get a lot smaller on their own.
Where to go next: the risk management page has the sizing and stop-loss math these fixes lean on. The psychology page covers what's happening in your head before any of this shows up on the chart.
