Been using time periods for trading... 5/15/60 minutes depending on instrument and time in trade... However, I have started to do analysis on tick charts. Tick seems to make sense for TA, as it shows the supply/demand over a number of trades, rather than time period. Seems to be a more clear way of showing price action and volatility, and would be a more true representation of momentum. Do you guys use tick or time? Thoughts?
