Multi-Period EMA Cloud — Trend Drop
The Multi-Period EMA Cloud stacks three EMA-pair clouds (fast, mid, macro) into one overlay so trend health is visible at a glance instead of cluttering the chart with raw moving averages. When all three clouds agree, you get an unambiguous "full bull" or "full bear" regime — when they disagree, you know to size down.
## What it does
- Plots four EMAs (default 8 / 21 / 55 / 200) and shades three clouds between them.
- Cloud color flips green/red on each pair's cross — fast = short-term momentum, mid = swing trend, macro = regime.
- Full-stack regime label in the corner shows FULL BULL / FULL BEAR / MIXED with the current EMA lengths.
- Optional background tint highlights bars where all three clouds agree.
- Alerts on full-stack flips and on the short-term (EMA1/EMA2) cross.
## Recommended settings
- EMA lengths: 8 / 21 / 55 / 200 (default)
- Source: close
- Show all three clouds: on
- Regime label: on
- Background tint: on
- Faster scalping variant: 5 / 13 / 34 / 89
- Slower swing variant: 10 / 30 / 100 / 200
## Ideal timeframe
Works on any timeframe; the default 8/21/55/200 stack is tuned for 15m–1D charts.
## How to use
Treat the clouds as a regime filter rather than a signal generator. When the macro (3-4) cloud is green and the mid (2-3) cloud is also green, only take long setups — let the fast (1-2) cloud time entries on pullbacks into it. Counter-trend trades become legitimate only when the macro cloud flips or when the mid cloud loses agreement. The full-stack alert is your "trend just confirmed in earnest" signal; the short-term flip alert is your early-warning that the underlying momentum is rotating.

# Multi-Period EMA Cloud
# Three stacked EMA-pair clouds (fast/mid/slow) give a layered, color-coded read
# on short, intermediate, and macro trend in a single overlay. Cloud color flips
# when the faster EMA crosses the slower one within the pair; full bull / full
# bear regime is signaled when ALL three pairs agree.
