I trade forex, every week I download my trades of that week and put all trades in a heatmap. I've been doing this for quite a while now, and with just one look I can see where I do good and where, not. I then take a screenshot and compare to screenshots of previous weeks. This gives me the ability, in a few seconds, just browsing through the screenshots to see if my changes in tactic and my bots, help and which way if more productive/profitable. To KonSchubert's point, scatter plots help when I have a small number of one or two dimentional attributes and it's pretty 'clean'. When I have multiple attributes (profit, duration of trade, etc) heatmaps work better (for me).
