Are charts completely arbitrary ? If so, this is somewhat disturbing. Consider the following two NinjaTrader candlestick charts. One is 144 tick, one is 150 tick. The 144 tick chart contains a harami @ 11:03:09 the 150 does not. Does this mean that chart representation is completely arbitrary (based on the series chosen) ? Chart 1 - 144 tick harami @ 11:03:09. Chart 2 - 150 tick no harami.
