01 / WHAT IT DOES

Get on in a big green week, get off in a big red one

Weekly average candles behind the chart

Big weekly average candles are drawn behind your daily candles: mint for green, coral for red, grey for small moves under 1%. The big trend shows at a glance.

1% body filter, closed-week signals

When a week closes with an average-candle body more than 1% green, buy next week; more than 1% red, sell next week. Smaller candles are ignored. Set on the closed week, so it never repaints.

Deciding price and a 9-week colour calendar

A dotted line and one sentence in the panel tell you which weekly close flips the signal. The panel also lines up the colours of the last nine weeks and this week like a calendar.

A signal on a closed bar never changes; only today’s unfinished bar can move.
No future data
Other symbols and higher timeframes use only data available at that moment, so no future values leak into past signals.

CALM CANDLE / FAQ

Frequently asked questions

What is Heikin-Ashi (the average candle)?

A chart that averages each candle with the one before it to smooth out noise. Its inventor is unknown; it became widely known through a 2004 US magazine article. Candlestick charts themselves are often credited to the 18th-century Japanese rice trader Munehisa Homma, though whether he invented them is uncertain.

What is the weak point?

Fewer than half of the trades win (24 of 52). In sideways markets small losses (−8.5% on average) come several times, and one big trend (wins average +53%) makes up for them.

Do signals change or disappear later?

No. They are calculated only from the closed week and never repaint. The indicator places no orders.

Do I have to watch the chart every day?

No. Look once when the weekly candle closes (Sunday 24:00 UTC). Buy and sell alerts are available too.

Can I use it on stocks?

You can add it to any daily chart, but the rule is tuned for crypto weekly candles such as Bitcoin and Ethereum. On stocks it did worse than just holding.

Can I edit or share the code?

You can edit it for personal use. Sharing, redistribution and resale rights are not included.

CALM CANDLE / HISTORICAL CASE

Bitcoin: bought at $11,374, sold at $49,121, 28 weeks later

BTC-USD · 1D · 2020.10 → 2021.04+331.0%

Bought the day after a week closed more than 1% green, sold the day after a week closed more than 1% red. The small wobbles in between were ignored.

90 days after the sale: −39.3%
Holding period: 28 weeks (about 7 months)

On 11 October 2020 the weekly average candle closed with a +2.95% green body, so it bought at the next day's open of $11,374.01. 28 weeks later, on 25 April 2021, the body closed −9.11% red and it sold the next day at $49,121. Within 90 days Bitcoin fell to $29,796.
