I still stand by my initial premise, trading gets progressively easier as the time frame rises.
I hear you there.
I suspect it depends a little on what people find "easier"/"more suitable"?
I don't think anyone can seriously question the proposition that TA-based "signals" get more reliable as the time-frame rises (though of course their frequency also dimishes: it depends to what extent one wants a trade-off between win-rates and trading frequency: my own perspective tends to be that it's better to take an average of 10 ticks four times a day than an average of 20 ticks once a day, or something like that, anyway).
I must admit my wife does pretty well with a system that includes a 3 tick chart on the ES. Super fast is not me.
Nor me ... I'm slightly surprised to hear the instrument selection, there: I would have thought she might prefer NQ to ES, for a 3-tick chart ... but obviously not (shows what I know about it!).
