CPR Trading Strategy: How to Identify Trending and Sideways Markets

The CPR trading strategy answers one pre-market question: will today trend, or will it chop? A common way traders lose money is by applying a trend plan on a sideways day, or a range plan on a trend day. CPR does not predict direction, but its width tells you which plan deserves your attention before the first candle forms.

In this guide I show how to calculate CPR, how to read narrow and wide ranges, how the two-day relationship adds context, and how to build a rule-based trade with Entry, Stop Loss and Target. More CPR lessons are on the Trading Direction blog.

What Is the CPR Trading Strategy?

The CPR trading strategy uses the Central Pivot Range from the previous session to judge how the next session may behave. A narrow range suggests compression and a possible trend day, while a wide range suggests a two-sided, sideways day. It is a planning tool, not a standalone signal.

The levels are fixed before the market opens and do not change during the day. That is why many Indian intraday traders like them: you can mark TC, P and BC in the morning and decide your plan with a calm mind instead of reacting to the first fast move.

Occasionally the formula puts TC below BC. When that happens, treat the higher value as the top of the zone and the lower as the bottom. The zone is what matters, not the label.

How Do You Calculate CPR and Its Width?

Pivot (P) = (High + Low + Close) / 3. BC = (High + Low) / 2. TC = (P − BC) + P. Width is TC − BC, and width % is that gap divided by P and multiplied by 100.

Always use percentage, not points. A 10-point CPR is tiny on NIFTY but very wide on a low-priced stock. Percentage lets you compare any instrument on the same scale.

Here is a useful detail. The CPR gap equals two thirds of the distance between the close and the midpoint of the day’s range. So a narrow CPR means the previous day closed near the middle of its range, and a wide CPR means it closed near an extreme. Both examples below are illustrative, not real sessions.

How Do You Identify a Trending Market with CPR?

A narrow CPR, with TC and BC very close to the pivot, suggests the market has compressed and a directional move is more likely. It does not tell you the direction. Wait for a clear 5-minute close above TC or below BC, supported by volume.

Chart logic: start with the width, then look at the opening. A gap away from a narrow CPR adds weight to that direction. Also check the distance to R1 or S1. If the next pivot level is only a few points away, the move has little room even if the CPR is narrow.

Published guides use different cut-offs for “narrow”, from about 0.3% of price in some broker articles to as much as 1% in scans discussed by traders. There is no official number. Pick one cut-off, test it on your own instrument, and keep it fixed.

How Do You Identify a Sideways Market with CPR?

A wide CPR suggests a two-sided session where price rotates between TC, BC and the pivot. Treat these levels as reaction zones, not breakout triggers. Breakout trades on such days see more false moves.

Chart logic: if price opens inside a wide CPR and keeps rejecting TC and BC, the day is behaving as a range. S1 and R1 often act as the outer boundary. A reaction trade needs a stop beyond the rejected edge and a target at the opposite side, and it should be small because ranges can break without warning.

One caution: a wide CPR can follow a strong trending day, and the trend can continue. That is why the two-day relationship and the first confirmed close matter more than width alone.

What Does the Two-Day CPR Relationship Tell You?

Compare today’s CPR with yesterday’s. A higher CPR shows value moving up, a lower CPR shows value moving down, and an overlapping or outside CPR points to balance.

• Higher value: today’s CPR sits above yesterday’s. Bullish bias, long setups get priority.
• Lower value: today’s CPR sits below yesterday’s. Bearish bias, short setups get priority.
• Overlapping value: the two ranges overlap. The market is in balance, so expect rotation.
• Inside value: a narrow CPR contained within the previous one signals compression and breakout potential.
• Outside value: the new CPR is wider and engulfs the old one. Many traders read this as sideways.

The cleanest days combine a narrow CPR with a higher or lower relationship that matches the opening gap.

Worked Example: Narrow CPR Breakout

All numbers are illustrative NIFTY-style points, not a real session. Costs, slippage and taxes are ignored to keep the arithmetic clear. Using the narrow day above: P = 24,805, BC = 24,800, TC = 24,810, and R1 = (2 × P) − Low = 24,870.

The Reward to Risk Ratio here is a teaching guideline. There is no official minimum, so set your own rule and apply it consistently. For index derivatives, quantity must follow the current lot size, so check it on the NSE site before you size a trade.

Common CPR Mistakes and Fixes

• Mistake: entering on the first touch of TC. Fix: wait for a candle close beyond it.
• Mistake: judging width in points. Fix: use width as a percentage of price.
• Mistake: assuming narrow CPR gives direction. Fix: let the first confirmed close, the gap and the two-day relationship decide.
• Mistake: taking a trade when R1 or S1 is very close. Fix: skip if the Reward to Risk Ratio falls below your own rule.
• Mistake: moving the stop inside the CPR after entry. Fix: place the stop at planning time and leave it.

My suggestion: write your cut-off and your stop rule on paper before the market opens. Rules written after a loss tend to be bent.

CPR Day-Type Checklist

• Previous high, low and close noted correctly
• Width percentage calculated and compared with my fixed cut-off
• Two-day relationship checked
• Opening gap and distance to R1 or S1 checked
• Entry, Stop Loss, Target and quantity written down
• Event calendar checked for the day

When NOT to Trade the CPR Strategy

• On a narrow CPR day when price keeps closing inside the zone
• When results or a major event can cause a sudden gap
• When the target level is too close to give your minimum Reward to Risk Ratio
• In the first few minutes, before any candle closes beyond TC or BC
• When you cannot define the stop before entering

Narrow CPR vs Wide CPR at a Glance

How Can You Scan for Narrow CPR Stocks?

Calculate width as a percentage of price for each stock after the close, then shortlist the ones below your cut-off. Apply the same confirmation rules the next morning. Keep the list short, because focus beats coverage.

Doing this by hand for hundreds of stocks is slow. A screener that flags narrow CPR names after market close helps you build tomorrow’s watchlist in minutes. Check how any screener defines “narrow”, and test it on a few past days before trusting it. I explain the full CPR framework in my published trading books.

Shortlist three to five stocks, not thirty. You can only watch a few charts properly at one time.

FAQ

Practical Takeaway

• Calculate CPR before the open and measure width as a percentage.
• Narrow suggests a possible trend day, wide suggests a range day. Neither gives direction.
• Let a confirmed close, volume and the two-day relationship decide direction.
• Fix Entry, Stop Loss, Target and quantity before the trade, and skip the day when the setup is not there.
