I was just browsing on youtube a little recently. OMG there's SO MANY people trying to sell their training. OMG they charge alot too -- like $200 a month or $1000 lifetime subscription, etc. I looked at some of their videos explaining how to trade. OMG BARF! Or they don't even show you what they really do LOL. Hey, maybe some are good, IDK, it just seems funny to me.

IDK why anyone would use heiken-ashi bars, IMHO I can't see what the point of them is. The purpose of renko is just to eliminate alot of the bars in between the swings, so you can fit more data on the screen, and just to make it easier to look at I guess. Point & figure is the same as renko but it doesn't show any bars in between the swings.

Range bars are the same thing as renko, except that they show the overlapping bars. However most software doesn't calculate renko exactly the same as range bars (like it should), so range bars are the #1 defacto standard. Plus sometimes the overlapping bars of range charts makes a 2-bar swing, when renko only makes a 1-bar swing, and since usually everyone wants to filter out the tiny 1-bar swings, then with renko you would miss that 2-bar swing.

About time charts, if the market moves fast then a bar may be large, so if an algo is waiting for each bar to finish before doing anything, then it'll miss some fast moves. Whereas range bars are always the same size so you know your algo won't miss any fast moves. Yet lots of people still use time charts. I guess they like losing money LOL.
