Tick charts versus time charts: same market, different story
Posted: Thu Oct 29, 2026 6:53 am
A time chart draws a new bar every minute, whether the market is busy or dead. A tick chart draws a new bar after a set number of price updates. The two can tell very different stories about the same period.
During quiet hours, a time chart shows a stream of small, dull candles, while a tick chart produces fewer bars, and each one covers a longer stretch of time. During bursts of activity, the time chart crams a lot of action into one bar, and the tick chart spreads it across many.
The advantage for scalpers is that tick charts normalise activity. Signals come in proportion to market action instead of the clock. Indicators behave more consistently, because each bar represents a similar amount of trading.
The disadvantages are practical. Tick counts differ between brokers, so a 200-tick bar on one platform may not match another. Backtesting on tick bars requires tick data. And many popular indicators were designed with time bars in mind.
A common approach is to keep a time chart for the big picture and a tick chart for entries.
Tick counts per bar also differ between brokers, which means a strategy tested on one broker's tick chart may behave differently on another. Documenting the exact tick number and the data source gives a reproducible setup.
Has switching to tick charts improved your timing, or did it just change the look of the noise?
