Overbought/Oversold
Assuming that the medium term trend is down it's preferable to use overbought readings of the Detrended Oscillator or its cross above the zero level. The Oscillator is now above the zero and possibly moving into the overbought. The levels to watch for short positions are 0.9918-0.9925 (confluence area of Fib resistances).
