Crypto Gann Fan: 1x1 Angles on Coins That Move 5% a Day
10 min read · Updated 9 Nov 2026
A Gann fan is a set of straight lines drawn from a major swing at fixed slopes. The central one, the 1x1, moves one unit of price per unit of time. Price on the trend side of the 1x1 is a strong trend; a close back through it is an angle break.
The trouble with angles on crypto is choosing the units: BTC trades near 75,000 and DOGE near 0.07, so "one dollar a day" means nothing. The page solves that with ATR, and that choice has a consequence on a market this volatile: the 1x1 runs away from price within a few weeks. This guide explains the rules, reads a real fan on ARBUSDT and BTCUSDT, and shows which lines are worth watching on crypto.
The rules
All four pages measure from major swings. A swing point comes from Gann's two-bar swing chart (see the crypto Swing Chart guide); it is major when its high or low is also the highest or lowest of the ten days on either side of it. Crypto has no holidays, so that is ten calendar days: a swing becomes major ten days after it is made, and until then the pages keep measuring from the one before it.
- The fan starts at the last major swing: drawn up from a low, or down from a high.
- One price unit is the 14-day ATR on the swing's date; one time unit is one daily candle, which on crypto is one calendar day.
- A line after t days = swing price ± ratio × unit × t, with ratios 4 (4x1), 2 (2x1), 1 (1x1), 0.5 (1x2) and 0.25 (1x4).
- Above 1x1 - the close is on the trend side of the 1x1 (above it for a fan from a low, below it for a fan from a high).
- Testing 1x1 - the close is within 1% of the 1x1.
- Broke 1x1 - yesterday on the trend side, today through it.
- Above 2x1 - beyond the steeper 2x1 line.
The crypto difference: the unit is large
ATR is the average daily range, so measuring in ATR makes a fan mean the same thing for a 75,000 coin and a 0.07 one. But crypto ranges are wide. Across the 30-pair sample from April to November 2026, the median 14-day ATR was 5.4% of price. A 1x1 that climbs 5.4% of the swing price every day, weekends included, is a pace few moves keep for long.
Drawn down from a high, the same line falls a full ATR a day and reaches zero after about 1 ÷ ATR% days: at 5.4%, about 18 days. The page does not stop it there, so a fan from a high a few weeks old can show a 1x1, 2x1 or 4x1 below zero. That is what the formula gives, not an error, and it tells you those lines are out of play.
A worked example: ARBUSDT from its 16 August 2026 low
The page's newest days when this was written, 7 and 8 November 2026, were a weekend and listed one pair and none (see the volume rule below), and past dates need a signed-in session. So the rows in this guide come from running the page's own Gann code on Binance spot daily candles grouped into IST days, the source of Unfluke's crypto archive. The page's figures for these days should match, or differ by a day where the archive's feed missed one.
ARBUSDT's 16 August low of 0.0722 became a major swing on 26 August, ten days later. The ATR on 16 August, 0.003499 (about 4.8% of the price), is the unit, so the 1x1 climbed 0.003499 a day.
- 1 September (day 16): ARB jumped 11.47% on 9.32× its average volume, but closed at 0.1069, still between the 1x1 (0.1282) and the 1x2.
- 3 September (day 18): it closed at 0.1371, above the 1x1 at 0.1352. Above 1x1.
- 4 September: it fell 4.08% to 0.1315, below the 1x1 at 0.1387. Broke 1x1.
- 5 September: back to 0.1428, 0.4% above the 1x1 at 0.1422. Above 1x1 and Testing 1x1 on the same day.
- 6 September: a 29.83% day to 0.1854, with a high of 0.2066. It stayed above the 1x1 through 8 September.
- 9 September (day 24): it closed at 0.1543 under the 1x1 at 0.1562. Broke 1x1 again.
- 10 September: the 31 August low (0.0831) became major, and the fan moved to it with a new, larger unit, 0.006326, because ARB's range had grown. The new 1x1 sat at 0.1464; ARB closed above it at 0.1494, then broke it on 11 September.
That was the end of ARB's 1x1 run, but not of the move: it rallied to a close of 0.2180 on 18 September. A 1x1 break says the pace has slowed, not that the trend is over.
How to use it in a trade
A step-by-step way to read a fan on a crypto pair:
- Read the Position column first. It says which two lines the close sits between. On 6 November BTCUSDT, drawn down from its 21 October high, was "Between 1x4 and 1x2": it had fallen a little faster than a quarter ATR a day.
- Treat the nearest line as the one in play. For BTC that was the 1x4 at 76,312.19, just above the close. A daily close back above it would say the decline has slowed to less than a quarter ATR a day.
- Ignore the lines far from price. BTC's 1x1 was at 50,554.77, a third below the close. ETH's, SOL's, LINK's and XRP's 1x1 lines were below zero. They are geometry, not levels.
- Check the swing's age. Days Since tells you how far the lines have travelled. A fan from a swing two months old has its 1x1 far from anything; a fan from a swing ten days old, as ARB's was in early September, is where the 1x1 tabs actually fire.
- Expect the fan to move. When a newer swing becomes major, ten days after it was made, the page redraws the fan from it with a new unit. ARB's did on 10 September.
Risk per trade - risk a small, fixed share of capital on any one idea. Crypto never closes, so a stop is the only exit while you sleep; with leverage, keep the liquidation price well beyond the stop. When selling options, prefer defined-risk structures (spreads, iron condors) over naked positions.
Strategy ideas (ideas, not promises)
These are ideas to study, paper-trade and backtest, not recommendations or signals, and not a promise of any result. Every condition below can fail. Crypto trades around the clock and can move sharply at any hour; leverage and options can lose more than you expect, and past behaviour says nothing certain about the next session. Size, entries, exits and risk are your own decisions.
1. A young fan above its 1x1
- Setup: the Above 1x1 tab with Days Since under about 20, like ARB on 3 and 5 September. On crypto these rows are rare (15 pair-days with the tag in the April to November sample), so each is worth a look.
- Idea: while closes stay above the 1x1, the move is keeping Gann's fastest pace. The session the pair appears on the Broke 1x1 tab is the exit to study.
- Check: on ARB, the first break (4 September) came back the next day. Test whether one close through the line, or two, works better on the pairs you trade.
2. Trade the slower angles
- Setup: a pair whose Position reads "Between 1x2 and 1x4", or "Between 1x4 and 1x2" on a fan from a high.
- Idea: on crypto the 1x2 and 1x4 do the work the 1x1 does on slower markets. A fan from a low whose close holds the 1x2 is still a steady advance; a fan from a high whose close stays under the 1x4, like BTC in early November, is a steady decline.
- Invalidation: a daily close through the 1x4, against the fan's direction.
3. Don't read a break as a reversal
The 1x1 climbs about 5% of price a day on a typical coin, so most moves fall behind it; that is a slowdown, not a turn. ARB broke its 1x1 on 11 September and made its high a week later. Pair a break with something that measures direction, such as a lower high on the Swing Chart.
Test before you trade - write the rules down exactly, test them on past data (see how to backtest an options strategy and the Option Simulator, which supports crypto), then paper-trade at least 20 occurrences before committing real money. Keep a journal of every trade, including the ones you skipped.
Every tab and column
- Tabs - All (every pair with a major swing to draw from), Above 1x1, Testing 1x1, Broke 1x1 and Above 2x1.
- Fan - From low (drawn up) or From high (drawn down).
- Swing Price / Swing Date / Days Since - where the fan starts, and how many daily candles ago.
- 1x1, 2x1, 1x2 - each line's value today. A value below zero means the line has run off the bottom of any real chart.
- Position - which two of the five lines (4x1, 2x1, 1x1, 1x2, 1x4) the close sits between.
- Tag - Above or Below 1x1 and 2x1 (depending on the fan's direction), Testing 1x1, Broke 1x1.

What the numbers are built from
- Pairs. The live USDT pairs in Unfluke's crypto archive (34 on 8 November 2026). A pair whose 20-day average range is under 0.25% of price is not scanned, which keeps stablecoins out.
- Liquidity first. A pair is listed only if its 20-day average turnover is above US$500,000, today's turnover above US$100,000, and today's volume above 0.8× the average of the previous 20 days. There is no circuit rule; crypto has no price bands.
- Days. Daily candles are IST calendar days, 00:00 to 23:59, rolled up from the one-minute Binance spot archive. Everything is end of day, and the newest day is topped up during the day, so it can be partial until 23:59 IST.
- Quiet days empty the page. The volume rule compares a day with the 20 before it, and weekends trade less. On Saturday 7 and Sunday 8 November 2026 most large pairs traded about a third of their average, so the Gann pages listed one pair and then none. A row can also drop out on a weekday: XRPUSDT closed exactly on its 50% level on Tuesday 20 October, on 0.79× its average volume, and was not listed.
- Day counts. "Days Since" on the Fan and Squaring pages counts daily candles; Time Cycles counts calendar days. On crypto these are the same number, except where the archive is missing a day (August and September 2026 have one each), when the candle count is one lower.
- Universe. All, Futures (pairs with a perpetual future in the archive) or Options (BTC and ETH).
- Prices. Shown to two decimals at 1 USDT and above, and to four significant figures below it, so 0.003499 is not flattened to 0.00.
Gann levels, angles and cycles are research references. They describe geometry on a price chart, not a forecast, and prices move through them regularly.
