Dan, you are absolutely right, in that if you have too many things to look at in real time, the analysis quickly becomes unmanageable. Also, your time frame has all to do with what sort of system will work for you. Daytraders pretty much need real time info, and there, three or four indicators are about the max your brain can integrate. For one day or more trades, however, a daily update near EOD is necessary and sufficient to determine where you are and to implement your signal, or if you prefer a confirmation strategy, to wait until NDO or next day EOD. In the latter case, your decision criteria can be extremely complex, limited only by your own imagination and programming skills, and once implemented, your criteria give the results you programmed (until you see the need to change it). The biggest challenge of course, is to believe what it is telling you absent the emotion and psychological head games to which we all fall victim, and just trade the system, not what you think the market *might* do.
