Old term - not sure if it's still "current," or even, come to think of it, if it's correct! I just remembered that it can mean something different for certain kinds of programming.
In this case, all it means is that, while I organize the gifs in separate directories initially by month, I name each trade in a way that makes searching for specific types easier.
The kinds of trades I do fall into a handful of main types: The first two letters of the file name describe which type. Next comes whether the trade was short or long, then whether it was a win, a loss, or a scratch, then the date by mmddyy format, then the particular tradable and then an optional character for additional trades of the same type on the same tradable on the same day:
bo_l=083002ZRAN would be a breakout trade (bo) from the long side (l) resulting in a scratch (=) today (08-30-02) in ZRAN. The idea, if you're not familiar with the technique, is so that if, say, I wanted to look at all losing long breakout trades from August I could search for "bo_l-08" or whatever
The trade review files will typically look something like what I've included below, and may sometimes include commentary or other details. The color-coded "paintbars" on the NDX chart relate to a TRIN-like indicator that I use. Most of the other indications have to do with critical levels like high of day, previous day's high, etc.
I try at a minimum to include everything that was decisive, along with time frame and key entries/exits. Sometimes I'll work in tick charts or dailies or 30-min charts. I only occasionaly try to save "real-time" screen views, but it might make sense to do some more of that (including l2 and T&S).
