What Is CISD?

From suspicion to proof

Before the CISD, there's only a suspicion. The market has taken liquidity and might turn, but "might" isn't a reason to trade. The CISD is the point where that suspicion becomes proof: the way price is being delivered visibly changes direction.

That distinction is the entire function of the concept. It separates traders acting on hope from traders waiting for change. The CISD gives you an objective moment instead of a feeling, and a feeling is exactly what becomes unreliable first under pressure.

Bullish and bearish CISD

A CISD has a direction. A bullish CISD means price was being delivered downward, and a candle then closes above the opening price of the run of down-closing candles that led there. A bearish CISD is the mirror image: price was delivered upward, and a candle closes below the opening price of the run of up-closing candles.

The close is what counts. A wick through the level is not a CISD. The body of the candle has to finish beyond it.

How to identify a CISD

1. Mark the liquidity. Find the level price just took: a previous high or low, or a cluster of equal highs or lows.
2. Find the run that delivered price there. Look at the candles that closed in one direction into that level. Note the opening price of the first candle in the run.
3. Wait for the close. Watch for a candle that closes beyond that opening price, against the earlier direction.
4. Mark the confirmation. The candle that closes through the level is the CISD. Before that close you have a suspicion. After it you have proof.

A CISD example

The numbers below are illustrative, not a real chart. Price closes lower for five candles in a row. The first of those candles opened at 100. Price then takes out a previous low. That is the liquidity. The next candle closes at 101.

101 is above 100, the opening price of the down-closing run. That candle is a bullish CISD. In SAM terms, the liquidity candle is candle 1 and the close through 100 is candle 2. What you do with that information is a separate decision. It belongs to your plan and your risk rules.

Where CISD sits inside SAM

SAM builds a setup across three candles. The CISD is the second step, the hinge the whole sequence turns on.

1. 01

   Liquidity

   The market takes out orders above or below a level. The setup forming.

2. 02

   CISD — the confirmation

   The delivery of price changes direction. This is where the setup becomes valid, not a candle sooner.

3. 03

   Expansion

   Price moves in the confirmed direction. Only now does execution come into view.

The full explanation of the sequence and the higher-timeframe context lives on the SAM page.

CISD vs CHoCH and MSS

Traders often mix these three terms up. They mark different moments.

A CISD is usually the smaller and earlier signal. It can appear before price has broken any swing point. CHoCH and MSS need that break first.

Why traders ignore the CISD

The CISD isn't technically hard to spot. Yet many traders enter before it, on candle 1, while it's still just a suspicion. That's rarely a knowledge problem. It's impatience: waiting for proof feels like letting an opportunity slip, and that feeling wins over the rule.

That's why a concept like the CISD is never enough on its own. You can know exactly what the confirmation is and still get ahead of it. Learning to hold the rule is psychological work, not additional technical knowledge.
