Yesterday was i of my meliorate days of the twelvemonth trading ES, in addition to a large business office of the success consisted of *not* next my process. Therein lies a tale in addition to why thus much mutual wisdom inward trading psychology is horseshit.
First off, at that spot is an underlying message you’ll withdraw heed from every furu: trading markets is actually easier than you lot think. Why is this the meta-message? Because the furu needs to appeal to the quick coin crowd. There’s no sexy message if you lot country people that trading is difficult; that fifty-fifty the earth aeroplane traders own got losing periods; that it takes years to principal whatever craft. So the furu goes afterward the people who *don’t* desire to locomote for a living. After all, what to a greater extent than alluring message to post than, “it’s actually easy…all you lot demand to focus on is X.”
Well, it’s non tardily in addition to there’s i major argue for why markets are thus hard to trade: they are ever changing. The marketplace position you lot traded 2 weeks agone is non the marketplace position that traded for the by 2 days.
Above is a nautical chart where each information indicate represents 50,000 ES contracts. It covers the menses from 7/1/15 to the present. Note how the rules that would own got made you lot coin real early on inward the menses are dissimilar from the ones that succeeded inward the middle of the menses in addition to extremely dissimilar from what has succeeded some recently.
I construct quantitative models of the ES market. The backtests for those short-term models own got gone dorsum to 2014, equally this has been a relatively stable (stationary) authorities (i.e., a stable railroad train of rules has been predictive of frontward cost movement). As nosotros went from trading Th to Friday, it became clear that the models (which mostly pose you lot long inward oversold, higher volatility environments in addition to brusque inward overbought, lower volatility periods) were non working. They were non working because the cost activity inward the marketplace position was non typical of the cost activity from which the models had been derived. Only the Oct 2014 menses was similar, only fifty-fifty at that spot of import differences were present.
(Parenthetically, nosotros unopen Fri amongst fewer than 5% of SPX shares trading to a higher house their three- in addition to five-day moving averages in addition to fewer than 10% trading to a higher house their 10-day moving average, amongst VIX having soared to 28. That cost activity is much to a greater extent than similar to 2010 in addition to 2011 atmospheric condition than 2014-2015 ones).
So I disregarded the model output in addition to instead turned to my query that identifies when nosotros own got a probable tendency day. The persistent hitting of bids on expanded book was indeed acquaint in addition to led to a skillful afternoon brusque trade. If anything, the models would own got had me hunting for bottoms.
I did non follow my procedure because I own got a meta-process for adapting my process. In other words, I am constantly scanning to run into if this fourth dimension actually is dissimilar thus that I tin strength out adjust to changing atmospheric condition equally apace equally possible. I don’t desire to locomote trading mean-reversion (which worked good through much of the menses of the nautical chart above) when we’re instantly inward a trend/momentum environment.
This is why trading is thus difficult. In some functioning fields, nosotros tin strength out count on stability: the pitching mound does non become from ninety feet from the plate to lx in addition to and thus 120. The basketball game hoop does non become from 10 feet high to 12 in addition to and thus 8-1/2. The rules of chess are constant throughout tournaments; the rules of markets tin strength out modify over the course of didactics of a week.
Success tin strength out come upwards from faithfully next your trading process. Ongoing success comes from apace recognizing when that procedure needs to adapt.
