US30 journal: how screenshot review caught rule breaks

[LondonScalper]

I take a screenshot at entry and at exit for every US30 trade. For years I barely looked at them. This summer I started reviewing them every Sunday, and it turned up rule breaks that my spreadsheet couldn't show.

The spreadsheet records times, prices, size and result. It said I'd taken 94 US30 trades between June and August, all within my allowed window of 14:35 to 17:00 London, all with stops of the correct size. On paper, perfectly disciplined.

The screenshots told a different story.

In 11 trades, I'd entered before the trigger candle closed. The spreadsheet showed the right entry price because the price was roughly the same, but the screenshot showed the candle was still forming. Those trades did worse than average.

In 7 trades, the stop wasn't at a structural level, just a fixed distance. The size of the stop was correct, but the placement wasn't.

That's 18 rule breaks out of 94 trades that I'd have sworn were clean.

The changes. I now review screenshots for every losing trade the same day, not just on Sunday. And I've added a column to the spreadsheet: "screenshot confirms rules: yes or no". It takes about 30 seconds per trade, and it makes it much harder to lie to myself.

Eighteen rule breaks out of 94 that looked clean on the spreadsheet is a usefully ugly number.

I started the same habit on US30 this year, and the early entry before the trigger close was my biggest leak too. On the sheet the price looked fine. On the screenshot the M1 candle still had two minutes left, and I was guessing the close.

My fix was slightly different. I moved the entry rule from "close of the trigger candle" to "open of the next candle after a confirmed close". That removed the temptation to click early, because there is nothing to click until the new candle starts.

The fixed distance stop that was not structural showed up in my review as well. Seven in your sample is not small. I now write the level name in the journal at entry, like "prior day high" or "15:00 swing low". If I cannot name it, the trade is not allowed.

Same day review of losers is the part I would steal first. Sunday is too late for the lesson to sting.

Did the "screenshot confirms rules" column change your size at all, or only your count of clean tickets?

The other leak screenshots caught for me was management, not entry. On about one in eight US30 winners I had moved the stop to break even inside the first minute, and the exit shot showed a normal pullback tagging it before price went on to the target.

The spreadsheet logged those as scratches, which looks harmless. Over the summer they added up to more than my early entries cost me, because the trades were right and I paid the spread to be out of them.

So I added a mid trade screenshot, taken only when I touch the stop. If the shot does not show a new swing low or high to justify the move, the column says no even when the trade made money.

I'd also push back gently on reviewing only losers the same day. Some of my worst rule breaks were winners, and a winning break teaches the habit faster than a losing one.

LondonScalper, did any of your 18 breaks end up as winners? If most of them lost, the screenshots might be flattering the clean trades a little.
