I trade the ZB, occasionally the ZN. Forget charts and candles. Order flow using the Jigsaw DOM is the best way to trade financials (IMO). If you're a scalper, order flow is an absolute must. You can't scalp financials off a 5-15 minute chart. Nobsdaytrading.com is the best education for scalping.
I do not think this is right. A better way to see order flow and the various competitions between market participants is with IB 5 second charts because the volume bars show the peeling and adding as Globex trades occur. My problem is that I am a philosophical type that needs a theory. Here is my probably wrong and delusional theory. The various market particpants in say ES are not algorithms because no data analysis program can adjust to suble pattern similarities well and fast enough (in the 1970s James Lighthill called this combinatorial explosion). The various seemingly random trades are either just fast human key pressers or semi automatic trade entry where a trader flips a switch and maybe is attempting to emulate a random number generator. My evidence for the existence of this is this Chat with Traders interview:
Will anyone admit their job is HFT program switch flipper?
