What is the 3-5-7 rule in trading?

ByMunyaradzi Mafaro

The 3-5-7 rule helps traders spot key price movement patterns that happen over 3, 5, or 7 days. These patterns show how prices move up and down in the market. Many traders use this rule to help them decide when to buy and sell.

This rule looks at price action over specific timeframes:

  • 3 days for quick changes
  • 5 days for medium-term moves
  • 7 days for longer trends

How the Rule Works

The main idea behind the 3-5-7 rule is pretty simple – prices often move in patterns that take 3, 5, or 7 days to complete. Here’s what happens in each timeframe:

3-Day Pattern

In a 3-day pattern, prices usually do one of these things:

  • Move up for 3 days
  • Move down for 3 days
  • Stay flat for 3 days

After 3 days, the price often changes direction. A stock that went up might start going down. One that went down might start going up.

5-Day Pattern

The 5-day pattern shows medium-term price moves. It often includes:

  • 3 days in one direction
  • 2 days in the opposite direction

Or:

  • 2 days in one direction
  • 3 days in the opposite direction

7-Day Pattern

The 7-day pattern captures longer trends. It might show:

  • 4 days up, 3 days down
  • 3 days up, 4 days down
  • Other combinations that add up to 7 days

Using the Rule in Trading

Here’s how traders put the 3-5-7 rule to work:

Entry Points

Traders watch for these patterns to decide when to enter trades:

  • After 3 days of price movement in one direction, they get ready for a possible reversal
  • During 5-day patterns, they look for trading opportunities in the middle of the pattern
  • In 7-day patterns, they try to catch bigger price moves

Exit Points

The rule helps traders decide when to exit trades too:

  • They might exit after 3 days if the price starts moving against them
  • They could take profits during 5-day patterns when the direction changes
  • For 7-day patterns, they might hold positions longer to catch bigger moves

Benefits of the 3-5-7 Rule

This trading rule offers several advantages:

Easy to Use

The rule uses simple numbers that are easy to remember and track. Traders don’t need complex math or fancy tools.

Clear Signals

The patterns give clear signals about possible price changes. Traders can spot them just by counting days and watching price movement.

Flexible Application

The rule works with different trading styles:

  • Day traders use it for quick trades
  • Swing traders use it for longer positions
  • Long-term traders use it to spot trends

Common Mistakes to Avoid

Here are mistakes traders often make with the 3-5-7 rule:

Counting Wrong

Some traders lose count of days or start counting from the wrong point. They need to:

  • Mark their charts clearly
  • Keep good trading notes
  • Double-check their counting

Ignoring Other Signals

The 3-5-7 rule works best when combined with other trading tools. Traders shouldn’t use it alone.

Following Too Strictly

Markets don’t always follow exact patterns. Traders need to be flexible and adjust when patterns break.

Real-World Examples

Here are some examples of how the 3-5-7 rule works in real trading:

3-Day Pattern Example

A stock moves like this:

  • Day 1: Goes up
  • Day 2: Goes up more

  • Day 4: Starts moving down

Traders watching this pattern might sell at the end of day 3 or start of day 4.

5-Day Pattern Example

The price action looks like:

  • Days 1-3: Moving down
  • Days 4-5: Moving up
  • Day 6: New trend starts

Traders might buy when the up movement starts on day 4.
