Grade the three inside up before you trade the continuation.
Upload a chart with a three inside up harami pause inside an uptrend and get a read on the contained middle candle, the breakout above the first candle's high, the trend leading in, the EMA position, the volume behind the confirmation, and a full trade plan, so a tight harami pause that resumes the uptrend and a stretched one that stalls do not get graded the same way.
HARAMI
The small second candle contained inside the first candle's range
BREAKOUT
The third candle closing above the first candle's high
UPTREND
The prior trend the harami pause sits inside
VOLUME
Whether the confirmation candle came on real participation

Sample readout
SNBR 1m bull flag pullback: strong opening momentum, lighter-volume consolidation, and a late breakout attempt with the 3.89 price marker near the current candle.
Quick answer
What is three inside up, and can AI grade it?
Three inside up is a three-candle bullish pattern built on a harami: candle one has a larger body, candle two is a small-bodied candle that sits fully inside candle one's high-low range, and candle three is a strong bullish candle that closes above candle one's high, confirming the move. It is one of the most heavily documented candlestick patterns, covered across Bulkowski's pattern statistics site and most technical-analysis education sites, and it shows up often on real charts. SnapPChart grades the WITH-TREND, continuation version of it: a harami pause that forms inside an existing uptrend, then candle three breaks above candle one's high to confirm the uptrend is resuming. That is the read the engine takes, a brief pause and resume, not the textbook bottom-reversal version where the harami appears after a downtrend and marks a reversal to the upside, because that is a counter-trend reversal and the grader does not trade those. From the chart you upload it reads candle one's range, whether candle two is genuinely contained inside that range, whether candle three closes above candle one's high, the prior uptrend context, the 9 and 20 EMA position, and the volume behind the confirmation candle, then returns a setup grade, an entry on the with-trend continuation, a structural stop below the harami, multi-target exits, and the bear case. It reads the image you upload, not a live feed, and it does not auto-detect or scan for the pattern, draw the candles for you, watch the tape, or predict the next candle. You mark the three candles, screenshot the chart, and upload it, and the same checklist runs every time so a tight harami pause that resumes a real uptrend and a loose one that really formed after a downtrend get judged differently.

Workflow
Use it as a quality check on the three inside up
Plenty of three inside up patterns fail when the harami really marks a bottom in a downtrend, candle two is not fully contained, or the confirmation candle comes on thin volume. SnapPChart gives you a consistent read on whether the pause is extending a real uptrend before you trade the breakout.
- Mark the three candles and screenshot the chart with the prior trend visible
- Check candle two sits fully inside candle one's high-low range, the harami containment
- Confirm candle three closes above candle one's high, the confirmation break
- Check the pattern is forming inside an existing uptrend, not after a downtrend
- Read the 9 EMA and 20 EMA trend context the pattern sits inside
- Re-grade after the move to see if it held, and skip the trade when the grade flags a loose containment, thin confirmation volume, or no clear prior uptrend
Head to head
SnapPChart vs a general AI chat assistant for three inside up setups
A general AI tool can spot three candles that look like a harami, but it will not judge whether candle two is genuinely contained inside candle one's range, whether the pattern sits inside an uptrend rather than at the bottom of a downtrend, or whether candle three actually confirmed above candle one's high, to the same standard twice. SnapPChart reads the containment, the confirmation break, the prior trend, and the volume the same way on every screenshot you upload.
| Feature | SnapPChart | General AI chat assistant |
|---|---|---|
| Grades the three inside up you marked on the screenshot | Yes, every upload | Inconsistent |
| Reads whether candle two is fully contained inside candle one's range | From the image | Varies by prompt |
| Checks candle three closes above candle one's high to confirm | Every grade | Rarely |
| Confirms the harami pause sits inside an uptrend, not a downtrend bottom | Every grade | Rarely |
| Flags a weak setup: loose containment, weak confirmation candle, thin volume | Every bear case | Rarely flagged |
| Entry, stop, targets off the with-trend continuation | Yes | Prompting required |

Three Inside Up AI FAQ
How SnapPChart grades a three inside up from your screenshot.
How does the AI grade a three inside up?
It reads candle one's high-low range, whether candle two sits fully inside that range, and whether candle three closes above candle one's high to confirm the move. It factors the prior uptrend, the 9 and 20 EMA position, and the volume behind the confirmation candle into the grade, then returns a setup grade, an entry on the with-trend continuation, a structural stop below the harami, and targets. A tight harami with a decisive break above candle one's high inside a clear uptrend on rising volume grades higher than a loose containment with a weak confirmation candle or no real prior trend.
Does it grade the bottom-reversal version of three inside up?
No. The classic textbook use of three inside up is a bottom reversal, the harami forming after a downtrend and marking a reversal to the upside, but that is a counter-trend reversal and SnapPChart's engine does not trade reversals. It grades the with-trend, continuation version: a harami pause forming inside an existing uptrend, confirmed by candle three breaking above candle one's high. If you mark a three inside up that is really forming at the bottom of a downtrend, the grade and the bear case flag that it is counter-trend, not the continuation the grader is built for.
How is three inside up different from three white soldiers?
Both are bullish, with-trend continuation patterns SnapPChart grades, but the structure is different. Three inside up is a harami-plus-confirmation pattern: a larger candle, a small candle contained fully inside its range, then a breakout candle above the first candle's high, a pause and a resume in three candles. Three white soldiers is three consecutive full-bodied green candles marching higher with no containment at all, a steady uninterrupted thrust rather than a pause. SnapPChart reads the containment and the breakout level for a three inside up, and the candle-by-candle thrust and wick size for three white soldiers.
Does SnapPChart auto-detect or scan for three inside up, or read live price?
No. It does not scan a feed for the pattern, draw the candles for you, watch the tape, or predict the next candle. You identify and mark the three candles, then screenshot and upload that chart, and the AI grades the structure it can see in the image: candle one's range, the containment of candle two, the break above candle one's high, the prior trend, the EMAs, and the volume. The grade reflects the picture you give it.
Can it tell a strong three inside up from a weak one?
It flags the weak-structure risk in the bear case. If candle two is not fully contained inside candle one's range, candle three barely closes above candle one's high on thin volume, the pattern is far extended from the moving averages, or there is no clear prior uptrend, the grade drops and the trade plan calls out that the continuation thesis is weaker. A clean containment with a decisive confirmation candle on rising volume inside a real uptrend grades better.
Is there a free trial for three inside up grading?
Yes. New users get two lifetime chart analyses. The first shows the full output so you can see exactly what the three inside up grade returns; the second is gated to show what the paid product adds. No credit card required.
