if you analyze on a tick level check the average volume traded per minute and how many ticks you supposed to to see over a second??? Keep in mind,that there are at least three middle chains that between you a tick you see on a chart: 1. exchange 2. data feed provider 3. chart provider As was mentioned above, look at the whole picture.
It's not a Harami on the 144 tick chart. Lets pretend it was a Harami or some other candlestick patterns, when you learn more about Japanese Candlestick Patterns, you'll understand that a specific candlestick pattern on one time frame will "sometimes" be a different candlestick pattern on a different time frame. Regardless, if you don't understand the big picture or the market context of the overall price action...you're going to have more difficulty in using chart analysis of any sorts as a technical analysis tool.
========================== Amen; in other words, 1 or 2 trees [or charts]in forest, ALMOST ALWAYS, means nothing.
Of course, and mostly everyone knows this crudity about time frames. What is also true and not arbitrary is the relationship of the fractals displayed on all charts. They are interlocking in a ratio of three to one as you view them going oooto ever slower fractals.
