How to Mark RSI Divergence Without Chasing Every Wiggle

Candlestick chart displayed on a monitor

Every new participant in our intensive arrives with the same habit: they mark every small RSI bounce as a potential divergence. By lunchtime on day one, the drill sheet looks like a connect-the-dots puzzle with no clear story. The fix is not a better indicator setting — it is a stricter rule for choosing which price swings count.

Start with price, not RSI

Before you glance at the indicator panel, mark the obvious swing highs and swing lows on price alone. An obvious swing high is a peak with at least two lower highs on each side — not a one-candle spike in the middle of a run. If you cannot defend a swing point without referencing RSI, it is probably too minor to use.

We ask participants to draw these swings in one colour on the printed chart. Only after all price swings are marked do we overlay RSI readings at those exact dates.

The two-peak comparison rule

A regular bearish divergence requires price to make a higher high while RSI makes a lower high at the corresponding points. Both peaks must be swings you already marked on price. Compare the RSI value at candle close for each swing date — not the intraday extreme unless you are working on a daily chart where close is the standard.

Common mistake: comparing a price high from March to an RSI reading from a minor April bounce that was never a price swing high. The divergence looks real on screen because the lines visually diverge, but the anchor points do not match.

Ignore the middle third of RSI during strong trends

When price trends cleanly, RSI often oscillates between 40 and 60 without meaningful swing structure. Divergences that matter usually appear when RSI has previously reached above 70 or below 30 and then fails to follow price on the next push. Mid-range wiggles in a trend are noise for divergence purposes.

Write the invalidation before you decide it is a signal

During study circle we require one sentence: "This read fails if price closes above [level] before RSI reaches [level]." If you cannot write that sentence, the divergence is not ready for a thesis — it is still a observation.

Practice suggestion

Take one daily chart of a VN30 stock you follow. Mark only the four most obvious swing highs from the past three months. Check RSI at each. If no divergence appears, that is a valid result — not a reason to add more swings until one appears.
