Total time 4 min.
============================
the above was taken from spydertraders journal thingy..
first i admit that i think this sct stuff is crap but trying to be objective i will tell you scientifically why.
if you look at what they have posted here see their perfect after the fact drawing of all their little lines? now watch the video of the tick playback, notice that the bars are different.
the compression i know is different cause the chart is compressing to scale as it builds. what i am talking about is you will see that there are open and closes and highs and lows that are different. the data that esignals and other data vendors supply is buffered and typically a best effort.
when relying on highs lows of a bar to draw lines its all going to fail apart that is the fallacy with line drawing methods. you can trust the volume to be transmitted accurately as well this clearly shows a lack of separation from real world trading.
in the real world you would know these things because you would have lost real money trying them. in short you can not trade using anything that is more than a general mean of the data.
i can talk lots more on this if be needed.
