That's how I use them - it takes time out of it and makes me focus on the price - regardless of how long it takes to move. I will say though I have found that a 233 tick bar takes way more than a minute to form.
Channel — I use a system similar to this. Another way to make the channel (i guess it's all the same but..) is to use bollinger bands with a small standard deviation, something like .25/-.25, whatever works for you. Also - in regards to rules ...
Tick Charts — I don't know if you're platform supports it, but I prefer tick charts vs. time charts. Takes the element of 'time' out of the equation and focuses simply on price action.
