What indicator source means
Most indicators calculate using the closing price by default. Source selection lets you change that — for example, running RSI on HL2 (the midpoint of High and Low) instead of Close, or computing an EMA on HLC3 (the average of High, Low, and Close).
The six source options
How to change the source
Open any chart in Punch.
Tap an active indicator to open its settings.
Tap the Source dropdown (shows "Close" by default).
Pick one of the six options.
Tap Apply.
The chart updates immediately and the status line confirms your choice — for example, EMA(20, HL2) = 105.42.
Which indicators support source selection
21 indicators have the Source dropdown: ALMA, Bollinger Bands, DEMA, EMA, GMMA, HMA, KAMA, Linear Regression, MA Cross, MA Envelopes, MACD, ROC, RSI, SD Channel, SMA, SMMA, Stochastic RSI, TEMA, VWMA, WMA, and Williams %R.
Indicators without source selection
Eight indicators use fixed inputs that cannot be changed: ATR, CCI, Donchian Channel, Keltner Channel, MFI, Pivot Points, PSAR, and Volume. These require specific price components (like both High and Low) to work correctly.
Good to know
Your source choice saves per indicator instance
You can run two copies of the same indicator with different sources — for example, EMA(20, Close) and EMA(20, HL2) on one chart.
For multi-line indicators like GMMA and MA Cross, the source applies to all lines in that instance. You cannot set different sources per line within one copy.
For MACD, your source choice feeds both the fast and slow calculations — there is no separate source per component.
Bollinger Bands supports source selection for its middle band (the moving average), but the upper and lower bands always use Close.
If you are unsure which source an indicator is using, check the status line — it always shows the current source in parentheses.
