1โฃ Wait, What's Log chart?
Before I define Log chart, let's look at the chart you are using daily - 'The Linear Chart'
- Linear chart is used by default in most platforms. This is probably why you never knew log charts
Wait, don't click on 'log' yet before you understand it...
2โฃ ok, so what does Linear chart mean?
Take a look at the image
- The y-axis is separated equally by 1000 points starting from 0 to 11000.
- So, any linear chart would have its y-axis equally separated by 'N' points always
And... that's where the problem lies...
3โฃ But, I don't see any problem?๐ค
Ok ok.. let me explain...
- Can you look at this #TATAELXSI chart & tell me the price in '99 when it was listed? No!
- Can you draw a proper trendline in this chart? No!
Reason is because of the price congestion between '07 to '20...
4โฃ What else?๐ง
- Whenever there is a price change in an instrument & it's drastic it'd be difficult to analyse on a linear chart
- Look at this example of #BTCUSD. What happened in 2021(refer to the red box)? ๐ค
All this is because of the equally spaced Y-axis!
hmmm... ok๐
5โฃ Let's talk about our hero - 'The Log Chart' ๐ฆธโโ๏ธ
Let's click on log first (refer chart)...
Do you see the change in the same #TATAELXSI chart? ๐(Reason in chart)
Yes, but what do you see?..
There you go!
- Price trend visible clearly
- You can identify trends since listing
6โฃ Here's a side-by-side comparison
- Basically a log scale considers the 'Percentage' price change in the Y-axis which makes a huge difference especially where prices have moved dramatically
- This dramatic price change could have happened in just a month or over many years
7โฃ Ok, so when to use log/linear scale
- See, in the short term charts log/linear scale don't make a difference (Refer chat)
- If you're purely an intraday or a short term trader, then you can continue to use linear charts
But, if price moves drastically(crypto) then use log...
8โฃ But, I am a long term investor + swing/positional trader?
Yes, then you ought to switch to 'Log chart' FOREVER so that...
- You can analyse charts properly
- Draw clean trendlines
- Identify primary trendline/channel reversals
Short term charts should be just fine with log!
9โฃ So, the next time you see a big handle analysing a long term chart with 'Linear chart' like this on #twitter ๐คฆโโ๏ธshare this thread on that tweet and kill it๐ช
And, yes switch to 'Log' now...๐ซก
๐ Learnt something? If yes, please๐
