hi..

I compared SF charts to another, and the volatility seems much lower on every stock on the stockfetcher charts??

I used same time frame (1 year) and logarithmic scale..
Actually the charts were a lot different in a strange way..
little confused here..

Thanks for answers, comments..

jayzz,

Log scale is based on the percentage move of the price and linear scale is a fixed scale with equal spacing of prices. So if you look at a stock like ABK that has dropped so much in the last year, it looks more volatile on the linear scale than it does on the Log scale.

Hope this helps,

trek

jayzz,

sorry, I see that you said you used log scale for both, I don't know what the difference in SF would be. I copied the phrase straight from the user guide and it appears to still be in Linear form.

aha..

For f.ex. finding trends, with about 1 year time frame,
would you recommend linear or logarithmic charts?
What does most traders use?



Thanks..

jayzz,

I personally use linear but sometimes will look at both if the stock has moved a lot.

For example look at ABK for the last year. The drop looks more dramatic on the linear scale than the log scale, but ABK seems to be making a bottom now which is hard to see on the linear scale unless you move to a shorter time frame. By using the log scale it shows up on the chart better.

Hope this helps,

trek
