I sat downwardly amongst a immature hateful solar daytime trader earlier the marketplace opened upwards in addition to asked his strategy for the morn session. "I'm bearish," he explained. "The markets convey all been downwardly overnight."
"Do yous know what the correlation is betwixt the overnight modify inwards the marketplace from closed to opened upwards in addition to the modify inwards the hateful solar daytime session?" I asked innocently. He shook his head, seemingly surprised that mortal would really inquire a query pertaining to data. "It's -.08 since 2007," I explained. "What happens overnight is non related to what happens during the day."
Our immature trader was unusually naive when it came to his short-term tendency following, but the fact remains that many short-term traders discovery their opinions colored past times what happened overnight. In reality, these business office every bit independent markets: what happens overnight is non predictive of what happens during the trading day.
A prissy instance of this independence is captured inwards the nautical chart above. I created 2 indexes, both educate to a value of 100 at the begin of 2007. The starting fourth dimension index (blue line) but adds the SPY points from closed to opened upwards to a running cumulative total. This is the "Night Market". The minute index (pink line) adds the SPY points from opened upwards to closed to a running total. This is the "Day Market".
Since 2007, the Night Market has gained 9.4 SPY points (the crude oil equivalent of 94 S&P 500 Index futures points). During that same time, the Day Market has lost 30.23 SPY points (about 302.3 S&P 500 Index futures points). For all practical purposes, the entire deport marketplace during 2007 has occurred during the trading day; non during overnight trade.
But if these markets are really independent, mightiness nosotros hold out able to best predict what volition occur during the hateful solar daytime past times limiting historical investigations to previous hateful solar daytime sessions? Could nosotros predict what is probable to occur overnight past times running studies on recent nighttime sessions? There's enough of room for master copy in addition to interesting enquiry past times segmenting marketplace days. More to come...
