I don’t think someone can say candlesticks are the best for everyone, it depends on what you’re looking for and how you’re looking at the data. If you’re setting up a program, then it won’t matter since you’re just pulling out data (ex. open/close etc..) if you’re using them to trade off the charts, the only downside is overlooking the highs/lows and only looking at the body, which can be a good or bad thing. I know most guys want to get rid of the noise, but there are many ways to accomplish that.

You have to try it and see if it fits your style, don’t try to just copy what someone else does, if you aren’t comfortable with it you won’t be successful over the long run

Deming et al and contemporary thinkers like Don wheeler and Davis Balestracci say; process behavior charts. A line chart with control limits (mathematically derived limits and that makes sense) gives more insight on the process which yields the data. It’s quite frustrating that such a simple concept of process behavior is not been tried by many. Well if you want to know more about it- I would recommend “Understanding variation” a 45 page book by Donald J wheeler, which talks about analyzing home runs in baseball to manufacturing process.
