• No restriction on combining Heikin Ashi with other free indicators in the same layout

Why this is usually paid for

Alternative chart types are often grouped into higher plans because they make a charting product look complete and are easy to separate from the basic candlestick view. Heikin Ashi itself is inexpensive to calculate, but access to several synthetic chart modes becomes a convenient tier boundary.

Basis performs the transformation in the browser from candles already loaded for the market. There is no data license specific to the visual form and no remote compute that needs rationing, so Heikin Ashi sits beside ordinary candles, Renko, Kagi, Line Break and Point & Figure without a paywall.

The important cost is conceptual rather than financial. Heikin Ashi smooths price by constructing synthetic OHLC values, which improves trend readability but removes exact tradable prices. Stops, limit orders and backtest fills should be checked against the underlying market candles, not against a synthetic close that may never have traded.

How to use it

1. 1

   Open the transformed chart directly

   Use the button below to load the terminal in Heikin Ashi mode. Begin with the same timeframe used for ordinary candles so the visual difference comes from the transformation rather than from changing two variables at once.

2. 2

   Use colour persistence as a trend description

   Runs of same-colour candles with small opposing wicks describe persistent directional pressure. Treat that as a filter for regime and trade management, not as a guarantee that the next synthetic bar will keep the sequence.

3. 3

   Switch to real candles before choosing a price

   Return to standard candles when marking entry, stop, target and support or resistance. The transformed high and low still use real extremes in the common formula, but the body prices are synthetic and can make a level look cleaner than the actual tape.

4. 4

   Avoid double smoothing

   A long moving average on top of already smoothed Heikin Ashi data can react far later than expected. Know whether an indicator is receiving transformed or raw candles and test the combined delay before using it as an execution trigger.
