Overlays reference

Overlays draw directly on the price chart, sharing the candles’ price scale. Nocterm ships ten: a set of moving averages, volatility bands, channels, and trend-following tools. Each carries its own parameters, editable from its legend chip’s settings gear.

A price chart with several overlays drawn on it - moving averages, Bollinger Bands, and a trend overlay

suggested 1280x720

Overview

Because overlays share the price scale, they read against the candles directly - a moving average that price rides, bands that contain it, a trend line that flips with direction. The defaults below are sensible starting points; every parameter is adjustable from the indicator’s settings gear.

How to use

1. Open the Indicators menu and add an overlay from the Overlays group.

2. It draws on the price chart. Open its legend chip gear to set the parameters listed below.

Overlays

Indicator	What it does	Key params
SMA	Simple moving average of price	Length (default 20)
EMA	Exponential moving average, weighting recent price	Length (default 21)
WMA	Weighted moving average	Length (default 20)
VWAP	Volume-weighted average price for the session	Session (no params)
Bollinger Bands	A moving average with volatility bands above and below	Length 20, StdDev 2
Keltner Channels	An EMA with ATR-based channels	EMA length, ATR length, multiplier
Donchian Channels	Highest-high and lowest-low channel over a window	Length (default 20)
Parabolic SAR	Trailing stop-and-reverse dots that follow trend	Step, max acceleration
SuperTrend	An ATR-based trend line that flips with direction	ATR length, multiplier
Ichimoku	Full cloud - trend, momentum, and support/resistance	Tenkan, Kijun, Senkou B

Tip

Pair a fast and a slow moving average (for example EMA 21 and SMA 50) to read trend quickly - price above both and the fast above the slow is a clean uptrend.

Note

Defaults are starting points, not rules. Adjust lengths and multipliers to your timeframe and instrument from each indicator’s settings gear.
