Grade the continuation diamond before you trade the breakout.
Upload a chart with a diamond pattern forming inside an uptrend and get a read on the broadening phase, the narrowing phase, the upper trendline the breakout has to clear, the volume behind the move, and a full trade plan, so a genuine two-phase diamond and a shape that only looks like one do not get the same benefit of the doubt.

Quick answer
What is a continuation diamond, and can AI grade it?
A diamond pattern forms in two phases that together trace a rhombus shape on the chart. First a broadening phase, where price makes higher highs and lower lows the way an expanding megaphone does, then a narrowing phase, where the range contracts into higher lows and lower highs the way a symmetrical triangle does. Four trendlines, two widening apart and two converging back together, outline the diamond. The pattern is more commonly discussed as a reversal signal near market tops, a 'Diamond Top,' but it can also resolve as a continuation: a diamond forming mid-uptrend that breaks out through its upper trendline to continue the move already in place. SnapPChart grades only that continuation case. It reads the broadening phase, the narrowing phase, the upper trendline the breakout has to clear, the prior uptrend the diamond is pausing inside of, and the volume behind the move, then returns a setup grade, an entry on the break above the upper trendline, a structural stop below the lower trendline or the most recent swing low inside the diamond, multi-target exits, and the bear case. It reads the image you upload, not a live feed, and it does not scan a symbol list for diamond shapes, draw the four trendlines for you, watch the tape, or predict the next candle. You mark the widening phase, the narrowing phase, and the prior uptrend, screenshot the chart, and upload it, and the same checklist runs every time. Continuation diamonds are also a genuinely uncommon pattern, rarer in real charts than triangles, flags, or wedges, so expect to see this setup less often than the site's other continuation patterns.

Workflow
Use it as a quality check on the diamond
Plenty of diamonds fail on a break that comes before the narrowing phase actually completes, or on a break of the upper trendline that lacks the volume to back it up. SnapPChart gives you a consistent read on whether this diamond is a genuine two-phase continuation setup inside an uptrend before you trade the breakout.
- Mark the broadening phase (higher highs, lower lows) and the narrowing phase that follows it, then screenshot the chart as price nears the upper trendline
- Check that the pattern genuinely widens first and then narrows, not just a loose cluster of swings that looks diamond-shaped in hindsight
- Confirm the diamond sits inside an established uptrend, so the break above the upper trendline is a with-trend continuation, not a top call
- Confirm volume expands during the broadening phase, contracts during the narrowing phase, and expands again on the breakout
- Read the 9 EMA and 20 EMA and trend context the diamond is compressing inside of
- Re-grade after the break to see if the upper trendline flipped to support or it was a fakeout, and skip the trade when the grade flags an incomplete narrowing phase, no clear prior uptrend, or a low-volume break
Head to head
SnapPChart vs a general AI chat assistant for continuation diamond setups
A general AI tool can tell you a chart looks like a diamond, but it will not judge whether the pattern genuinely widened before it narrowed, or whether the upper trendline break is a with-trend continuation and not a top call, to the same standard twice. SnapPChart checks the broadening phase, the narrowing phase, the upper trendline breakout level, and the volume the same way on every screenshot you upload.
| Feature | SnapPChart | General AI chat assistant |
|---|---|---|
| Grades the continuation diamond you marked on the screenshot | Yes, every upload | Inconsistent |
| Checks the broadening phase against the narrowing phase that follows it | From the image | Varies by prompt |
| Reads the upper trendline and the with-trend breakout level | Every grade | Rarely |
| Flags a diamond that never widened, or a low-volume break | Every bear case | Rarely flagged |
| Entry, stop, targets off the with-trend break | Yes | Prompting required |
| Never grades the diamond as a top-calling reversal | Continuation only | May call a top |

Continuation Diamond AI FAQ
How SnapPChart grades a continuation diamond from your screenshot.
How does the AI grade a continuation diamond?
It reads the broadening phase you marked, the higher highs and lower lows, the narrowing phase that follows it, and how price is compressing toward the upper trendline where the diamond's two phases meet. It factors the with-trend breakout level, the 9 and 20 EMA position, the uptrend context, and the volume behind the move into the grade, then returns a setup grade, an entry on the break above the upper trendline, a structural stop below the lower trendline or the most recent swing low inside the diamond, and targets. A diamond that genuinely widens and then narrows inside an uptrend, contracting on falling volume and breaking out with-trend on building volume, grades higher than a loose cluster of swings that only looks diamond-shaped in hindsight or a break that comes on thin volume.
How is a continuation diamond different from a symmetrical triangle?
The number of phases. A symmetrical triangle is a single, continuous convergence from the start: the descending resistance line of lower highs and the rising support line of higher lows converge together the whole time. A continuation diamond is two phases. It first widens, higher highs and lower lows, the way a broadening formation does, and only after that does it narrow into something that looks like a symmetrical triangle. So a diamond is a broadening formation that transitions into a symmetrical triangle, not one continuous narrowing pattern. If your chart only ever narrows and never widens first, you are looking at a symmetrical triangle, not a diamond, and the symmetrical triangle page is the right one to use.
Does SnapPChart grade the diamond top reversal pattern, or only the continuation breakout?
Only the continuation breakout. The diamond pattern is more often discussed as a reversal signal, a 'Diamond Top' that calls a market top after an uptrend, with price breaking down through the lower trendline. SnapPChart does not grade that case at all. It grades one honest instance: a diamond forming mid-uptrend that breaks out upward through its upper trendline to continue the existing uptrend. It never calls a top, never grades a downside breakdown, and never produces a short or reversal setup. If the diamond you are looking at is sitting near what looks like a market top and you expect it to break down, this page is not the right tool for that read.
Does SnapPChart auto-detect or scan for continuation diamonds, or read live price?
No. It does not scan a feed for diamond shapes, draw the four trendlines for you, watch the tape, or predict the next candle. You identify and mark the broadening phase and the narrowing phase and the prior uptrend, then screenshot and upload that chart, and the AI grades the structure it can see in the image: the two phases, the upper trendline, the EMAs and uptrend context, and the volume. The grade reflects the picture you give it.
Can it tell a real continuation diamond from a fake one?
It flags the weak-structure risk in the bear case. If the pattern never actually widened before it narrowed, there is no clear prior uptrend for the break to continue, or price broke out early on thin volume, the grade drops and the trade plan calls out that the continuation thesis is weaker. A diamond with a genuine broadening phase followed by a genuine narrowing phase, sitting inside an uptrend and breaking out with-trend on building volume, grades better. Continuation diamonds are also a genuinely uncommon pattern in real charts, rarer than triangles, flags, or wedges, so do not force the label onto a shape that does not clearly show both phases.
What should be on the chart before I screenshot it?
Make sure both phases are visible: the broadening swings of higher highs and lower lows, and the narrowing swings that follow of lower highs and higher lows, along with the candles, timeframe, price scale, and volume. Marking the four trendlines, the two widening and the two converging, helps, since the read is about whether the pattern genuinely widens first and then narrows. The 9 EMA and 20 EMA add the uptrend context the grade factors in. The more of the prior uptrend and the breakout area that is visible in the image, the more complete the read.
Is there a free trial for continuation diamond grading?
Yes. New users get two lifetime chart analyses. The first shows the full output so you can see exactly what the continuation diamond grade returns; the second is gated to show what the paid product adds. No credit card required.
