What Is Cause and Effect in Trading?

Also known as: law of cause and effect, Wyckoff cause and effect, cause and effect trading, how far will price move after a pattern, target sizing by timeframe

Definition

Cause and effect is the rule that the size of the move you expect has to match the size of the structure that causes it. A pattern on a small timeframe causes a small move, and a range built on a higher timeframe can cause a large one. A 15 minute pattern can't carry a target that needs a daily-sized move.

Most targets don't fail because the direction was wrong. They fail because the trader asked a tiny pattern to deliver a giant move.

The pattern is the cause, the move you expect is the effect, and the two have to be in proportion. It comes from Richard Wyckoff's law of cause and effect: the length of a trading range sets the potential size of the trend that follows.

This is for traders who know where a trade is going before they click. If you see an M on the 15 minute chart and picture a crash to the lows... read it twice.

Why can't a small cause make a big effect on a chart?

A double top that formed over three hours on the 15 minute chart holds three hours of orders. A three-week double top on the daily holds three weeks. The move tends to scale with the structure behind it.

Timeframe imposition explains why: 15 minute structure builds 4 hour structure, 4 hour builds daily, and daily builds weekly. A 15 minute pattern is usually one swing inside a 4 hour range. Its effect is the NEXT swing, not the end of the 4 hour trend.

In Chad's charting, a 15 minute M pattern (double top) is typically good for around a 3 to 5% move. That's an observation, not a rule, and volatility can stretch it. Most traders assume far more.

Small cause, small effect.

What does a cause and effect mismatch look like with real numbers?

Illustrative numbers. BTC is near $80,000 and prints a clean M pattern on the 15 minute chart.

  • Entry: short at $79,800 after the neckline breaks and retests.
  • Stop: $80,350, above the M highs, $550 away.
  • Size: 1% of a $10,000 account is $100; $100 divided by $550 is 0.1818 BTC, rounded down to 0.18 BTC.
  • Congruent target: the low end of that 3 to 5% range, about 3% below the $80,000 top, near $77,600. That is $2,200 from entry, a ratio of 1:4, which passes the 1:3 filter.
  • Mismatched target: $65,000. The ratio looks spectacular on paper, but it asks a few hours of structure to produce a move of nearly 19%.

The first trader takes profit where the cause supports it. The second watches price hit $77,600, bounce and come back through the entry. Move the stop? Hold and hope?

Same entry. Same direction. Only one had a plan the chart could fill.

Where does the cause and effect check live in our process?

It's the third question in top-down analysis: where am I trading from, and where am I trading to? Targets go at the next structure on the timeframe that matches the cause. Higher timeframe targets need higher timeframe structure behind them.

In Chad's words: "It's only a good trade if you know the cause and what to expect on the effect." And: "We need to anticipate the effect to be in congruence with the cause."

Wyckoff is the source. The timeframe calibration, and the habit of checking it before every single target, is ours. Inside the Decision Protocol, the check lives in the entry and exit plan, before size is finalized. Every time.

What's the cause and effect mistake that gets people liquidated?

Small pattern, huge target. A trader shorts a 15 minute double top expecting a fall of tens of thousands of dollars, holds like it's coming, and gives back what the pattern delivered. Add high leverage and it gets ugly, right? The normal pullback after a small cause reaches a liquidation price that was set for a much bigger story.

Crypto YouTubers love drawing that arrow to the floor off a 15 minute chart. It gets clicks, not fills.

The reverse stings too: a weeks-long structure resolves, the trader grabs a 15 minute profit and watches the real move leave without them. Match the target to the cause both ways.

What cause and effect check should you run before your next trade?

Write down the pattern's timeframe and the move that timeframe usually delivers. If the target needs more, cut it or skip it.
