MACD in Crypto: Warm-Up Bars and Short-History Errors

MACD needs a 26-bar EMA plus a 9-bar signal before its first full reading — and its EMAs keep depending on the starting point after that.

Short answer

MACD(12, 26, 9) needs at least 26 bars for the slow EMA and 9 more for the signal line, so the first histogram value appears around bar 34. Because EMAs are recursive, values continue to depend on the series start for many more bars; on a coin listed a few weeks ago, or a short data pull, MACD crosses can differ from those computed on long history. Drop early bars and compare with a longer series before trusting crosses.

Recursive smoothing: values depend on where the series starts and settle only gradually.

Why does history beyond that matter?

EMAs are recursive.

What about new coins?

Treat early MACD as unreliable.
