Price has moved far from its average: when is a pullback worth considering, and when is it too early?

01What "far from the average" actually means

First you need an average to measure from. The usual one is a moving average of the last 20 candles: add up those 20 closing prices, divide by 20, and you get a line that follows price with a delay. When someone says price has run far, they mean far from that line.

On top of that line, traders draw two more lines — one above, one below — placed so that price almost always stays between them. In the app this setting is called Bollinger Bands. How wide the two lines sit is set by a number next to them (in the settings menu it is often labelled StdDev or deviation), and 2 is the default: a bigger number pushes the lines further apart, a smaller one pulls them in. With that default, price stays inside the two lines something like 85% of the time, so a close outside them really is unusual.

When a candle does close outside, you have measured one thing and one thing only: this distance is unusual for the last 20 candles. The lines say nothing about what happens next — they tell you how rare today's stretch is, not where price goes tomorrow. Everything else is your reading of the situation around it.

You only need one set of settings to begin. Start with 20 candles and the width at 2 — that is what the app gives you by default. If you want the lines tighter for a quiet market, drop the width to 1.5. Write down whichever pair you pick and leave it alone while you test; otherwise you will never know whether the idea works or just your latest tweak.

02Why the same candle can mean the exact opposite

Here is the uncomfortable part. A confirmed close above the upper line is also the entry signal of the squeeze breakout approach — there, the same candle means "a big move is starting, join it", with a stop under the middle average and a trailing exit. One event, two opposite trades. If you are curious about that reading, it has its own page on how to spot a squeeze with Bollinger Bands.

What separates them is the state of the market before the candle. When the two lines pull tight together, the usual reading is that a big move is coming in one direction or the other; when they stretch unusually wide, the trend may be heading into a pause or a turn. And when price taps the lower line again and again, it can mean the coin has been sold so hard, so fast, that sellers are running out — what traders call oversold — or it can simply mean there is a level down there that keeps holding. Nobody has a rule that tells those apart in advance, and anyone who says otherwise is selling you hindsight.

The practical consequence: before you look at the distance from the average, look at the kind of market you are in. If the last several days have been a back-and-forth between two zones, a stretch has something to come back to. If price is making one new extreme after another and each candle closes outside again, you are standing in front of a moving train. Sorting that out first is the whole subject of is the price trending or just going sideways, and it belongs before the indicator, not after.

03What one trade looks like in money

Take an illustrative case on Bitcoin. You have 300 USDT in your futures account and you open a 500 USDT short at 5x, so about 100 USDT is set aside as your margin and the rest stays free. Price has pushed above the upper line, the next candle closes back inside, and you sell at 83,000 with a stop above the high of the stretch.

If price drifts back to the middle average — about 1% lower — your 500 USDT position earns 5 USDT. If you enter and exit with market orders, Bybit charges about 0.28 USDT each way on a 500 USDT trade at the base fee level, around 0.55 USDT in total, so you keep roughly 4.4 USDT. If instead the move keeps going and price runs 2% against you before your stop fills, that same position loses 10 USDT plus the same 0.55 USDT of fees, so about 10.6 USDT leaves your account. Hold a perpetual across a settlement and funding adds or subtracts a little more.

Look at those two numbers side by side. The winner is small because the target is the middle line, and the loser is bigger because a stretched market can stretch further. About four and a half dollars up, about ten and a half dollars down. You can be right more often than you are wrong and still finish the month behind — and every extra trade pays its fees whether it works or not.

04Write the entry condition and the cancel condition before you enter

An idea becomes testable the moment you can say, out loud and in advance, what would make you take the trade and what would make you drop it. Here is a version you can write on one line and then check against history. The numbers are mine for the sake of a clear example, not a published rule — change them, but change them before you trade, not during.

1. State the market condition

   On the 4-hour chart, price has turned back from roughly the same high zone and the same low zone at least twice in the last two weeks, and there is no run of new extremes in one direction. If you cannot say that honestly, there is no trade today.

2. State what "far" is

   On the 15-minute chart with the 20-candle average and the width at 2, one candle closes fully outside the lines. Write those exact settings in your notes so the next test uses the same ones.

3. State the trigger

   You do not enter on the candle that ran out. You enter only after the next candle closes back inside — and you take the trade in the direction of that return.

4. State the exit and the stop first

   The target is the middle average. The stop goes beyond the extreme of the stretch, and you size the position so that reaching it costs the amount you decided earlier, not a round figure you typed in a hurry. The mechanics are on how to set a stop loss.

5. State the cancel condition

   If a second candle closes outside in the same direction instead of coming back, the setup is dead and you do not take it. If you are already in and price makes a new extreme beyond your stop level, you are out — no widening, no "it must turn soon".

6. State when you drop the whole idea

   Decide in advance what would make you stop using this approach on this coin — for example, a run of setups where the cancel condition fired before the trigger. Writing that down now is easier than deciding it after a loss.

05How to test it without paying for the lesson

Start with history, because it is free. Open a chart with your chosen settings, scroll back a few weeks, hide the right side of the screen with a sheet of paper, and step forward candle by candle. Each time your condition appears, write down the date, whether the trigger or the cancel came first, where your stop and target were, and what actually happened. Thirty lines in a notebook will teach you more about this idea than thirty articles — including which markets it never works in.

Then test the same rules forward, in real time, with no money at stake. A demo futures account gives you the actual order window, the actual fees and the actual feeling of a stop sitting a little too close; the guide to opening a demo futures account on Bybit walks through it, and you can sign up on Bybit and switch to demo before you ever fund anything. Check that your chosen contract exists in demo before you build a plan around it, and check that futures are available where you live while you are signing up.

If this is your first approach rather than your fifth, read it next to the broader picture in which futures strategy suits beginners — and keep in mind that the opposite idea, catching a reversal after a long rally, has its own set of checks. The good thing about this idea is that it fits on one line. Write your line, check it against a few weeks of history, and you will know within an evening whether it is worth any of your money.
