As weblog readers know, I postal service each morn earlier the marketplace pose opened upwards a series of proprietary cost targets for the S&P 500 Index (SPY). These Twitter posts summarize the prior day's Pivot grade (an approximation of the day's average trading price), also equally iii upside targets (R1, R2, R3) in addition to iii downside targets (S1, S2, S3). The targets convey been empirically derived to accommodate for recent marketplace pose volatility so that, dorsum to 2000, to a greater extent than or less 75% of all trading days volition hitting either R1 or S1; 50% volition hitting either R2 or S2; 33% volition hitting either R3 or S3.
Days--and periods of days--where nosotros don't hitting whatever of these targets are attain outflow days. These tend to cluster, given series correlations of volatility. Thus we'll convey periods of fourth dimension inwards which nosotros hitting 1 or to a greater extent than targets in addition to periods of fourth dimension inwards which we'll remain closer to daily pin levels. Much of the science of trading, across whatever fourth dimension frame, is identifying when we're inwards a directional marketplace pose environs (and so probable to hitting the cost targets) or a attain environs (and so probable to oscillate about pin levels and/or volume-weighted moving averages).
Once nosotros define the pin in addition to cost target levels for a item day, nosotros tin inquire some rather sophisticated questions. For instance, if nosotros hitting R3 or S3 inwards yesterday's trade, what are the odds of hitting the R1 or S1 grade today? If nosotros produce non hitting either R1 or S1 inwards today's trade, what are the odds that we'll convey a directional motion (i.e., 1 that hits 1 or to a greater extent than cost targets) tomorrow?
Notice that, the sectionalisation of marketplace pose moves into R1/R2/R3 in addition to S1/S2/S3, each adjusted for that market's grade of volatility, provides us alongside an objective mensurate of a day's directionality. We tin in addition to so inquire whether stronger upwards or downwards days (those that hitting R2/S2 or beyond) are to a greater extent than probable to Pb to reversal than days that alone hitting R1/S1.
Such investigations are probable to uncover trading patterns that furnish a possible border to traders. For example, did y'all know that the marketplace pose ii days from at in 1 trial (e.g., Monday's market) has a 43% adventure of touching today's (Thursday's) pin level? If nosotros part relative book into the mix, those odds ascension substantially. Knowing that nosotros convey high odds of a attain marketplace pose over a swing trading menstruum could live quite valuable to both twenty-four hr menstruum traders in addition to those belongings overnight.
To overstep away fifty-fifty to a greater extent than ambitious, imagine that nosotros calculate similar pin in addition to cost targets for diverse sector ETFs in addition to stock indexes. We tin in addition to so inquire such questions as, "What happens when the S&P 500 Index touches R1/S1 today, but fiscal stocks (XLF) produce non hitting their R1/S1?" If a sector hits its R1 early on inwards the trading day, what are the odds that the S&P 500 Index volition follow in addition to hitting its R1 target? Do for certain sectors tend to Pb the S&P 500 inwards hitting their targets?
All of these investigations offering potential conclusion back upwards for traders, in addition to Twitter is an ideal machinery for blasting the results of these investigations to traders inwards existent time. More to come--
