When to Use Log Scale on TradingView
Linear scale gives equal height to equal price changes; logarithmic scale gives similar height to equal percentage changes. Charts spanning several multiples often read better in log.
Build the chart or workflow
Choose the scale before long-term trendlines or cycle comparisons and label screenshots. Short-term orders and fixed-cash risk still require exact price levels.
How to interpret the result
A move from 10 to 20 versus 100 to 110 looks different because linear emphasizes absolute change and log emphasizes proportion. They answer different questions.
Common failure modes
Drawing on log and then keeping the same visual conclusion on linear changes the meaning of slope and support.
A repeatable checklist
- Choose horizon
- label scale
- compare percentages
- verify order price
- redraw trendlines after changing scale
Can this be used as a standalone trading signal?
No. Treat it as one piece of context. Price structure, liquidity, execution cost, and a predefined invalidation point still decide whether a trade is justified.
When should the setup be checked again?
Recheck whenever the symbol, exchange feed, interval, session definition, or indicator input changes. Those choices can materially change what the chart shows.
