Quote from romik:
Here are my thoughts on chart analyses. While reviewing EOD charts is a must for anybody who is serious enough to consider doing this for a living or even as a supplementary income (not loss basically) it is just as important to study charts real-time and applying your previously gained knowledge on real-time charts. Do not get trapped by hindsight analyses, as in hindsight one may very easily not see POTENTIAL price oscillations, as it is already there on the plate for us to see. Doing that all the time will not train your mind to be ready to react in due time, reaction lag does happen a lot to the majority (I assume here) novice traders. Nihabaashi (ET member) has posted a lot of quality stuff on both of these subjects. He recommends using programs that record daily price oscillations (charts) and later reviewing them that way, rather than simply looking at the EOD charts, which is easy stuff. I think he mentioned Camstasia, though some charting programs offer this function built-in or as an add-on.
I would say real time is much more important than studying the daily chart.
I also think that is why paper trading any technique is so important before "graduating" to real money. It is important you can see the setups in realtime as they evolve.
One reason daytrading is so much more difficult than longer term trading is time pressure. Usually within a few minutes of seeing a setup you have to come to a firm decision, yes or no, and if yes pull the trigger. Then you have to manage the trade consistently even when it may go against you while watching it all unfold realtime. If it is going against you, you may be tempted to close prematurely to stop the perceived pain. Yet, if it goes for you, you may be tempted to close prematurely to ensure you have a profit no matter how small. Boy, is it tough.
One chart package that has the playback facility built in is Ensign Windows which can be used very efficiently with an IB data feed.
It is my experience, and belief, that doing premarket analysis on stuff like the daily chart is not as important as you would think. Far more important to see the reality of the market unfolding before your eyes and always be ready to go long or short regardless of any preconceived biases you may start the day with.
Cheers.
