3. When to Use Log rather than Linear

4. Summary

-- Logarithmic Charts Explained --

Logarithmic or log price scale, represents price spacing on the vertical or y-axis dependent on the PERCENTAGE CHANGE in the underlying asset's price

Think of it as the log scale shows the rate of change over time

-- Linear Charts Explained --

Linear or arithmetic price scale, represents price on the y-axis using equidistant spacing between the designated prices / the absolute values

Think of it as showing the absolute number increase / decrease over time

-- When to Use Log rather than Linear --

Traders tend to use log for Long-Term perspective or when price movements are large / in multiples

Linear scale is used more by Day traders within tight ranges

-- Summary --

 I use Log when looking at HTF's and trying to find confluences with trend lines / pitchforks etc...

 I find with Bitcoin due to the large % price moves I tend to keep my charts on Log

 NOTE: Some @tradingview indicators have specific log scale settings
