i use one minute charts....but, it makes sense to use a longer time frame...will experiment with 5 minute.
1, 5, and 15. 5, and 15 on the corresponding index. 3 price patterns on all 3 time frames = trifecta and high probablility.
For those rare occasions where I stick around and watch price action 5 minute chart is by far the best. For the life of me I can't understand why anyone would use 1 minute chart since it is filled with insane volatility.
creation of patterns (price action) with volume on the 1 minute can be very powerful if you are interpreting correctly. I agree the 5 is stronger and allows for better position size calculations.
When you use tick charts, what is the most critical element of change you watch for? A percentage in price; quantity of ticks within varying time frames?
