Definition: I have added a 52-week , which is a measure of market , the band widen when the underlying instrument is volatile, while it narrows or squeeze when the underlying instrument gets in-volatile. Traders use in different way, one of them is to monitor when the bands squeeze which hints a breakout is imminent, as such periods of in-volatility usually followed by strong moves.
BB on TLT/SPX: The band has been narrowing for a while following the 2008-2009 crash, to a very narrow range within the past year or so, indicating the ratio is at a very in-volatile stance.
-Average True Range(ATR): The ATR is another indicator of , without going into too much details about the construction of this indicator, in short it's constructed through a formula that compare the range of each period.
ATR on TLT/SPX: Its visually very clear on the chart, the indicator moves higher when major moves in the ratio occur, starting from the left, the ATR line was high but moving lower following the 2000 market crash, where it dropped below the pivotal zone(colored in YELLOW) to the GREEN zone. The green zone clearly indicates a low environment. A break out from this green zone to the RED zone, signaled a pick up in , and either a market crash or a hefty correction. as shown on chart. The ATR line is currently in the green complacency zone, as the recent test of the yellow zone failed to break higher to the RED area.
Putting Both together: without looking at any other technical studies(such as levels) , and looking solely on studies, what we got now is a squeeze, and ATR within the green zone, that might not be an immediate signal, but at least its another warning signal, that tells we are ready and possibly close to a major move. I will keep my eyes on the ATR now for a break above that sensitive zone in yellow.
