Continuing yesterday's initial look at XIV and VXX here are views of the 130 minute bar charts of each with a 2 standard deviation, 14 period Bollinger Band (BB) overlay and an 8 period moving average band of the high and low (blue band). This is really all you need to trade these varmints,.... everything else should be considered confirmation signals.
The strategy here is to watch for violations of the BB followed by a reversal of 2 bars. The threshold triggers are noted by the vertical purple lines. Note the position of the RSI2 in each instance...this should also be regarded as a confirmation signal of an impending trigger.
The charts indicate the current BB intersects as ripe for a reversal although entries right now should be considered premature and risky.
NOTE: this BB setup is configured for XIV and VXX. Lower beta ETFs and stocks seldom produce reversal signals as clearly defined when using this layout.
