Bollinger Bands for Scalping

TL;DR: Bollinger Bands are a volatility indicator. Scalpers use them primarily to spot "the squeeze"—a period of extreme volatility compression that precedes a massive breakout.

While many retail traders use Bollinger Bands as dynamic support and resistance (buying the bottom band and selling the top band), this strategy fails miserably in crypto scalping during strong trends. Instead, professional scalpers use Bollinger Bands to measure volatility compression.

The Anatomy of Bollinger Bands​

Bollinger Bands consist of three lines:

  1. The Middle Band: A Simple Moving Average (SMA), usually set to 20 periods.
  2. The Upper Band: The Middle Band + 2 Standard Deviations.
  3. The Lower Band: The Middle Band - 2 Standard Deviations.

The distance between the upper and lower bands represents the current market volatility.

Trading the Bollinger Squeeze​

The most powerful setup using Bollinger Bands is the "Squeeze".

  1. Identification: When the market enters a Narrow Range, the upper and lower bands will pinch tightly together. The tighter the squeeze, the lower the volatility.
  2. The Principle: Volatility is cyclical. Periods of extremely low volatility are always followed by periods of extremely high volatility.
  3. The Trigger: Wait for the price to aggressively break out of the squeezed bands on high volume. This is your signal to enter the trade in the direction of the breakout.

[!IMPORTANT] Never try to predict the direction of a Bollinger Squeeze before it happens. Wait for the initial impulse and order flow confirmation to avoid getting caught in a Fakeout.
