On this 5 minute chart of BHI and SLB, an alert was generated at 9:45am when the SD crossed back over LB1. The spread went back to its mean at 11:15am, creating a nice $.64 profit. SD RSI confirmed. SD MACD slowly starts to confirm.
In this example from DO and RIG, we bought the spread at -$1.70 (since DO and RIG trade very close in price, the spread sometimes is negative) after an alert is given at 9:50am. We sold the spread at $-.95 at 11:05am, for another nice profit of $.85!! Again SD RSI is rising and although the SD MACD isn't positive yet, it is also rising.
This example in WAG and CVS shows you the power of the ISB Indicator. It shows that highly correlated stocks can revert back to their means many times a day. On this chart the SD reverts back 4 times in one day! Each one good for about a $33 cent profit!
