Null
"I trade the gap back to nothing."
Every morning, the stock market opens at a price that is different from where it closed the day before. This difference is called the "overnight gap". Null's entire strategy is built around one simple, data-confirmed fact: most small overnight gaps disappear within the first 30 minutes of trading.
The price drifts overnight because the market is very thin — few trades are happening, and the small volume can push prices around artificially. When the real market opens at 9:30 AM ET with all its volume and institutional participation, those artificial overnight price movements tend to get corrected fast.
Null waits for the overnight drift to start correcting, enters the trade in the direction of that correction, and targets the prior day's closing price as the destination. When it arrives there, Null exits. Simple, disciplined, and backed by data.
Imagine yesterday's closing price is a solid anchor, the absolute zero of the desk. Overnight, when the main trading desk is asleep, the market drifts into the domain of Erebus — the primordial god of darkness and the void. The thin volume allows the price to wander into the shadows, stretching away from the anchor point.
At 9:30 AM ET, when the day begins and the full light of the market shines, the overnight shadows are swept away. The price is pulled back into the void toward the anchor point — returning to zero. The bigger the overnight stretch, the harder the pull, but Null only trades small drifts where the return to absolute zero is highly predictable.
Null's job: confirm that price has wandered into the domain of Erebus, wait for the pull back to zero, and ride that reversion.
This isn't a theory. It's been statistically validated across 2,791 trading days of NQ futures data (2014–2024). The fill rates for gaps that revert to the prior close are:
Tiny gaps (less than 0.3× the daily average range): 78% fill by close
Small gaps (0.3× to 0.7× daily average range): 42% fill by close
Large gaps (over 1.2× daily average range): 8% fill by close
Timing: 61% of all fills happen in the first 30 minutes
This is why Null only trades small gaps. A gap that's less than 0.7× the average daily range is very likely to fill. A large gap — driven by real news, a genuine fundamental shift — does not fill. Null's filter keeps it away from the traps.
During the night, the whispers of Nyx and Erebus deceive travelers with illusions of distance. The thin overnight volume is like those whispers — easily creating an artificial price spike or drop. When Apollo rises at 9:30 AM with the bright sun of institutional volume, these nocturnal illusions are immediately corrected back to reality.
If the deception was too extreme (a huge gap), perhaps a real change occurred in the landscape. Null skips those. It only targets the minor deceptions — the ones that are easily dispelled by the morning light.
1. Measure the gap. Calculate the difference between yesterday's closing price and today's opening price. Divide by the average daily range (ATR). If the gap is between 0.1× and 0.7× the average range, proceed. Too small = not worth trading. Too big = probably real news, skip.
2. Check the calendar. No trades on Fed announcement days, jobs report days, or major inflation data release days. These can create large, genuine moves that don't fill. Hard rule.
3. Check the trend. If the Nasdaq is in an uptrend overall (above its 20-day average), Null only trades gap-DOWN fades (expecting price to bounce back up). Counter-trend gap fades in strong trends are riskier.
4. Check pre-market volume. If pre-market trading volume is more than 2× the usual amount, institutions are very interested in today's gap direction — possibly because they know something is real. Skip the day.
1. Wait for the open drive. Don't enter at exactly 9:30 AM ET. For the first few minutes, the market tends to continue in the gap direction — retail momentum chasers are still piling in. Let it play out.
2. Wait for the reversal candle. Watch for a single strong candle that retraces at least 50% of the open drive in one move. This is the moment institutions begin absorbing the retail momentum.
3. Find the Fair Value Gap. That strong reversal candle creates a tiny price imbalance (the same Fair Value Gap concept as Wicker). Enter at the midpoint of that zone as price drifts back into it.
4. One trade per day, maximum. Null is not a high-frequency strategy. One clean setup per morning, then done.
Yesterday's closing price — the gap fill. Null takes 50% of the position off when the price has covered half the gap, then holds the other 50% to the full fill at the anchor point.
Sometimes the gap fills and price just keeps going. For these "gap fill and continuation" days, Null uses a trailing stop to capture the extended move without giving back all the gains.
Placed beyond the Fair Value Gap zone. If price pushes back past the entry zone from the wrong direction, the thesis is wrong — exit immediately.
If the gap hasn't filled by 11:00 AM ET, Null exits at market. Data shows that after 11:00 AM ET, the probability of the gap eventually filling drops to just 6–7% per hour. The bet no longer makes sense. Get out.
Null has an 82% win rate — which sounds amazing. But there's a critical nuance that makes this strategy more fragile than it appears on the surface: the losses are bigger than the wins.
On average, when Null wins, it makes about $98. When it loses, it loses about $145. This is called an "inverted win/loss ratio" — you win more often, but each win is smaller than each loss.
In the Underworld, the Danaids are condemned to carry water in sieves to fill a bath. They manage to add small drops of water continuously (many small wins). But every now and then, a leak sweeps away a large amount of their progress (a larger loss). To make headway, they must carry water exceptionally fast and keep their win rate extremely high (above 65%). If the win rate drops, their basin will drain faster than they can fill it.
This is why Null's paper trading requires 100 trades before any real capital commitment (vs. 60 for Wicker). The inverted ratio means a bad streak hits harder. More data is needed to confirm the win rate is truly holding.
If Null's win rate drops below 65% in live trading (from the 82% backtested), the strategy becomes unprofitable — the average loss size overtakes the average win size. Rolling 20-trade win rate is tracked continuously.
Measure the gap size. Check the economic calendar. Check pre-market volume. If any filter fails, the day is called — no trade. If all pass, prepare to watch the open.
The open drive begins. Retail traders chase the gap direction. Null watches patiently and does not enter.
The moment a strong single candle retraces 50%+ of the open drive, the FVG is identified and the limit order is placed at the midpoint. If this doesn't happen by 10:30 AM ET, the session is a no-trade.
50% off at the halfway point, 50% off at the full prior close. If it runs further, trail the stop and let it breathe.
If the gap hasn't filled, exit at market. The thesis has expired. Move on.
