NIFTY 50 breadth thrust
A breadth thrust is a sudden shift from most stocks falling to most stocks rising. This strategy tracks the share of NIFTY 50 members that advance each day, smooths it with a 10-day EMA, and buys NIFTY futures when that average jumps from below 40% to above 61.5% within ten sessions. The position is held for 25 trading sessions with no stop or target, rolling to the next contract at each monthly expiry.How it trades

PRE-BUILT · DEFAULTSWhere it made and lost money
One signal in the year cannot show which conditions suit the strategy. The single position was split by a monthly roll: the first part lost ₹19,526 and the second, entered on a choppy day with a gap up while NIFTY was below its 20-day average, lost ₹1,60,537. The rules have no stop, so once the rebound behind the thrust failed, the long position took the full fall in March 2026 until the 25-session exit. The episode shows the main exposure of the design rather than a pattern: a breadth thrust that turns out to be a bear-market bounce is held all the way down.
About this strategy
- Each day, take the number of NIFTY 50 stocks that advanced and declined, and compute the advancing share: advances divided by advances plus declines.
- Smooth that share with a 10-day EMA.
- A signal fires when the EMA closes above 61.5% after having closed below 40% at some point in the last ten sessions. A fresh close below 40% is needed before the next signal.
- Breadth is only known after the close, so buy one lot of near-month NIFTY futures at 15:15 on the following session.
- Hold for 25 trading sessions and sell at 15:15. There is no stop loss and no target.
- On each monthly futures expiry day, close at 15:15 and buy the next month's contract at the next session's first tick.
- Signals that appear while a position is open are ignored.
Why traders use it
When almost every stock in an index goes from falling to rising within two weeks, it often marks a washout followed by broad buying. Historically such thrusts have been rare and have tended to come near the start of a recovery, which is why the indicator has a strong following among breadth-focused traders. It uses only advance and decline counts, so it is easy to compute from daily data.
The year in plain words
From 1 Oct 2025 to 30 Sep 2026, the NIFTY 50 breadth thrust fired once, in February 2026. That single position appears as two trade records because it was rolled at the monthly expiry. Both parts lost: ₹19,526 before the roll and ₹1,60,537 after it, as NIFTY fell sharply in March while the strategy held long with no stop. The total was a ₹1,80,063 loss before costs and ₹1,80,552 after ₹20 per order and bid-ask slippage. One signal says almost nothing about whether the thrust works, but it shows how large an unprotected 25-session futures hold can lose.
What the settings do
Risks
- There is no stop loss, so a long futures position is fully exposed for about five weeks.
- Signals are rare; one bad signal decided the entire year here.
- Overnight gaps and global events over a 25-session hold can move NIFTY by thousands of points.
- The holding period was chosen on past data, so it may not suit a different market phase.
Who it suits
Positional traders who follow market breadth and can hold a NIFTY futures lot for several weeks with enough margin for deep drawdowns, accepting very few trades a year.
Questions traders ask
What is a breadth thrust?
It is a rapid change in market breadth: the share of stocks advancing goes from very low to very high within about two weeks. Here the 10-day average of advancing NIFTY 50 stocks must move from under 40% to over 61.5% within ten sessions.
Is the breadth thrust strategy profitable on NIFTY?
In this test it fired once and lost ₹1,80,063 before costs and ₹1,80,552 after ₹20 per order and bid-ask slippage, from 1 Oct 2025 to 30 Sep 2026. A single trade proves nothing either way, and past results do not guarantee future ones.
Why is one trade shown as two?
NIFTY futures expire monthly, so a 25-session hold usually crosses an expiry. The expiring contract is closed and the next month's is bought, which appears as two trade records for the same position.
Why not use other breadth measures like new highs?
Measures such as the share of stocks at a four-week high need each stock's own daily prices. This test only has daily advance and decline counts, so it uses the thrust built from those counts.
