Day Trading Setups
Trend Day vs Range Day Classifier
The first few bars of a session never announce what kind of day it's going to be. Set how many bars you get to see, make your call, then watch the real classification get computed honestly off the full session, not off a hidden label.
Set the reveal, call it, then check the real math
The slider controls how many of the session's real opening bars you get to see before you have to call it. Once you predict Trend Day or Range Day, the rest of the session plays out bar by bar. When it's done, the tool computes the real classification straight from the complete bar data, net move divided by total range, and grades your early call against that number.
Move the slider, then make your call.

How it works
- The classification is computed once, from the full real session. Net move is the absolute distance from the session's opening price to its final close. Total range is the sum of every single bar's own high-to-low range across the whole session.
- The ratio decides the label. Net move divided by total range above roughly 0.30 gets called a Trend Day, price actually went somewhere relative to how much it moved around getting there. Below that line it's a Range Day, plenty of motion, little net progress.
- Your call is graded against that number, never against a hidden setting. The bars you see before calling it are generated the same way every time, there is no separate flag telling the tool what kind of day it secretly planned to be.
- The per-N table isolates whether more bars actually help. Every N you've tried gets its own running accuracy, so you can see directly whether waiting for 15 bars beats calling it off 5.
Where this breaks
A late reversal can erase a real trend from the classifier's point of view
The ratio only looks at where the session opened and where it closed. A session that trends hard for most of the day and then gives most of it back in the final bars can still score as a Range Day, even though anyone watching it unfold would have called it a trend for hours. The reverse also happens, a single outsized bar near the close can push a genuinely choppy session's net move high enough to score as a Trend Day. The classifier is honest about the full session's numbers, it just doesn't know or care what order those numbers arrived in.
