SET Wave Update: The Decision Zone Was Reached — Here's What Price Actually Did

Track. Study. Wait. Strike.
English อ่านภาษาไทย (Thai)

Four weeks ago I published a wave count on SET with two scenarios and one specific decision zone: 1,644 – 1,674. I said the level mattered more than the count, and that how price behaved there — not whether it got there — would be the real signal.

Price got there. This is the follow-up, including the part where I grade my own call.

What actually happened

SET climbed into the zone and tagged 1,657.55 on 21 July — inside the range I'd named, in its upper half. Then it was rejected: a slide to 1,587.29 on 30 July, about −4.2% off the high. It has since recovered to 1,623.64.

SET Index reached the 1,644-1,674 decision zone, was rejected to 1,587, and recovered to 1,624 while the 1,450 floor held

So the zone did what a decision zone is supposed to do: it produced resistance, and it produced a reaction. Now the useful question — which scenario is that reaction feeding?

The scorecard

What I said in JulyWhat happenedVerdict
Resistance in the 1,644–1,674 zoneTopped at 1,657.55, then rejectedCorrect
Scenario 1: pull back but hold above ~1,450Pullback stopped at 1,587 — nowhere near 1,450Holding
Scenario 2: reverse hard, threaten the old lows−4.2% and already recoveringNot triggered

On the evidence so far, Scenario 1 is the live one. A −4.2% dip that finds buyers 137 points above the invalidation level is a shallow, healthy correction — which is precisely what Scenario 1 predicted. Scenario 2 required a hard reversal, and a 4% wobble isn't that.

The honest caveats

Three things keep this from being a victory lap.

First, it's early. The pullback is nine trading days old. Corrections can go sideways for weeks and still resolve either way. "Scenario 1 leading" is not "Scenario 1 confirmed."

Second, the zone hasn't actually been cleared. SET topped at 1,657 and sits at 1,623 — still below the zone, not above it. Scenario 1's full confirmation needs price to eventually take out 1,674 on the next attempt. Until then, this remains a rejection that held its floor, not a breakout.

Third — and I'll keep repeating this — none of this is a system signal. Everything else we publish is backtested. This wave count isn't, and our own Elliott-Wave-3 gate test was falsified: when we tried to turn wave counting into a mechanical rule, the edge we found came from the confirmed pullback low and a tight stop, not from the Elliott labels. So read this as a map of levels — system state — not as a reason to act.

What I'm watching next

Price is doing something narrower and more useful than either scenario's dramatic version: it reached the level, respected it, and held its support. That's a market building a base under resistance, and the resolution is worth waiting for rather than predicting.
