Timing the bottom is almost impossible. Instead, look for buy signals. When the ROC indicator goes from mega oversold (-20) to mega overbought (+20), along with the KST either showing a positive divergence or weekly MA crossover and a McClellan Oscillator (measure of market breadth) mega oversold (-70) to mega overbought (70) is the signal I would look up for!
