Hi Griff!
That 10 min chart is pretty much standard.
The first few years I traded, I spent most of my time chasing butterflies. I scratched the surface on a lot of different concepts, but wasn't where I wanted to be. I realized that I needed to pick something, and stick with it. I chose the 10 min dow.
I've traded using the 1,5,10,15,30,60/daily/weekly/monthly charts. They are all good, and they all have a place. In a fast moving market like we are in now, the whipsaws will kill a slow chart. When the market is trending, longer time frames work better.
Many different strategies will work. The problem is, the market changes. It's similar to fishing. Fish will generally do different things at different times of the year. What works on shallow spawning fish doesn't do as well in cold weather when they are deep. Matching the proper strategy to the condition will help determine which tool to use. The catch is being able to properly identify the condition, WHILE its happening. It's easy to look at a chart after the fact or tell us what was done earler. That helps teach a lesson, but it doesn't put any money in the account.
