VIX spike dip-buy
This is a fear-buying strategy. When India VIX, or a price-based fear gauge called the Williams VIX Fix, reaches the top 1-2% of its recent history, the strategy buys NIFTY futures at the next day's close and holds for four sessions. The idea is that panic tends to overshoot, so buying when fear is extreme can catch the rebound. It trades rarely and has no stop loss.How it trades

PRE-BUILT · DEFAULTSWhere it made and lost money
With only 15 trade records, no condition has enough trades to judge, so these figures describe what happened rather than a pattern. The outcome simply followed the market during the hold: the 4 trades where NIFTY rose more than 1% made ₹1,11,467, and the 4 where it fell more than 1% lost ₹1,30,221. Entries on choppy, wide-range days lost ₹1,57,053 over 8 trades, which fits the idea that fear readings in the middle of a volatile, undecided market were early rather than at the bottom. With no stop, the rule has no way to cut a trade when the panic continues.
About this strategy
- At each close, rank India VIX against its previous 100 closes, and do the same for the Williams VIX Fix calculated from NIFTY futures daily bars.
- The Williams VIX Fix measures how far today's low sits below the highest close of the last 22 sessions, in percent.
- A signal needs at least one of the two ranks above 98 and at least one above 99.
- On the session after the signal, buy one lot of near-month NIFTY futures at that day's closing print.
- Hold for four more sessions and sell at the close of the fourth. There is no stop and no target.
- If the futures contract expires during the hold, it is closed at expiry and the remaining days are carried in the next month's contract. New signals are ignored while a trade is open.
Why traders use it
Volatility spikes usually come with sharp sell-offs, forced selling and headlines that push prices below fair value. Because volatility tends to fall back after a spike, buying near the peak of fear is a long-standing contrarian idea. Combining India VIX with a price-based fear measure means the signal can fire even when the VIX itself is calm but the index has just made a deep drop from its recent high.
The year in plain words
From 1 Oct 2025 to 30 Sep 2026 on NIFTY, the signal produced 15 trade records (some are one position split across a contract roll). Only 5 were winners and the strategy lost ₹45,226 before costs, a profit factor of 0.73. Wins averaged ₹24,022 and losses ₹20,667, so sizes were large either way. One month decided the year: March 2026 lost ₹1,15,479, which was also the maximum drawdown, while February and April made ₹37,739 and ₹46,130. After ₹20 per order and bid-ask slippage the loss is ₹49,415.
What the settings do
Risks
- There is no stop loss, so a long futures position is fully exposed for four sessions during the most volatile periods.
- Signals are rare, so a handful of trades decides the whole year; one losing trade cost ₹65,981.
- Overnight gaps are fully taken because the position is held across several sessions.
- The thresholds come from earlier research on other data and may simply not fit the current market.
Who it suits
Positional traders interested in contrarian, volatility-based entries who can hold a NIFTY futures lot through big swings, keep enough margin for overnight moves, and accept very few trades a year.
Questions traders ask
What is the Williams VIX Fix?
It is a price-based fear gauge: the distance between today's low and the highest close of the last 22 sessions, as a percentage of that close. It rises when the market falls sharply from a recent high, so it behaves like a volatility index built only from price.
Does buying NIFTY when India VIX spikes work?
In this test from 1 Oct 2025 to 30 Sep 2026 it lost ₹45,226 before costs and ₹49,415 after ₹20 per order and bid-ask slippage, with a maximum drawdown of ₹1,15,479. A single month of continued falling wiped out the gains. Past results do not guarantee future results.
Why are some trades split in two?
NIFTY futures expire monthly. If the four-day hold runs past the contract's expiry, the old contract is closed at the expiry-day close and the remaining days are carried in the next month's future, which shows as two trade records.
How often does the signal fire?
Rarely, because one of the gauges must be in roughly the top 1% of its last 100 readings. Over the test year it produced 15 trade records including roll splits, and signals that appeared while a trade was already open were ignored.
