Acceleration bands

What does Acceleration bands measure?

A price envelope that breathes with the market. It sits around the average price and stretches wider when candles get tall, so a break outside it means a genuinely unusual push.

How is Acceleration bands calculated?

Take the 20-candle average price for the middle line. For each candle, work out how tall it was compared with its own price level, multiply that by 4, and push the high and low out by that much — then average those pushed values over 20 candles for the two bands.

Written by reading the engine’s real computation, not a textbook — where the two differ, the page describes what actually runs.

How do I use Acceleration bands in a bot?

In the builder, add an indicator of type accbands (parameters: length, default 20). Its output series — upper, mid, lower — become operands you can compare in any entry or exit rule. The engine grades the whole rule honestly: real fills, no look-ahead, half the history held back.
