Measured across 6,083 candidate intraday setups, betting against the last 5-minute candle is right about 60% of the time. Here is why that number is a trap.
When we built the SwipeTA question bank, we ran every dumb rule we could think of against it before we let a single question near a player. One of them did unreasonably well.
The rule is: look at the last 5-minute candle before the decision point; call the opposite way. Green candle, swipe down. Red candle, swipe up. No context, no levels, no volume — one candle.
Across the 6,083 candidate setups we scanned, that rule is right roughly 60% of the time.
Five minutes is short. At that resolution a large part of what you are looking at is not a move, it is the mechanics of a move being absorbed: a push into a level and the immediate answer to it, a sweep and the snap back, a burst of size and the vacuum behind it. Mean reversion at that timescale is not a market opinion, it is close to a description of how a limit order book digests a shove.
So a naive contrarian rule catches a real property of intraday price action. It is not noise, and it is not an artifact of our selection — it is there in the raw candidate pool before any filtering.
Two reasons, and the second is the one that costs money.
It fails four times in ten. A rule at 60% with no notion of when it does not apply is a rule you cannot size. You have no way of telling the setups where it holds from the setups where you are standing in front of a trend that is only just getting started — and those are exactly the ones that run furthest against you.
Knowing it makes you worse at the thing you were trying to learn. This is the part we did not expect. If you internalise "fade the last candle" you stop reading the chart, because a rule that works most of the time removes the reason to look at anything else. You are then very well prepared for the 60% of situations that were going to resolve themselves anyway, and completely unprepared for the 40% that were not.
That is a bad trade for a training tool. The whole point of practising is to build the judgement that tells those two cases apart.
We could have removed every question the naive rule answers correctly. That would have been worse: a bank where fading the last candle always fails is just as solvable, in the other direction, and players would learn a rule that is wrong in the real world.
What we do instead:
Do not use it as a rule. Use it as a null hypothesis.
When you look at a frozen chart and your instinct says "this pushes back", ask whether you are reading the chart or whether you are just doing the thing that is right 60% of the time. The setups where those two answers differ are the only ones that are teaching you anything.
The mechanics of how these questions are built, filtered and judged are written out in full on the methodology page.
