Agree, the sto is not going to tell a change in trend, the Macd positive/negative cross of its signal will. Also a rising ADX with a directional indicator following will complement the Macd cross to show a "sustained" move either upward or downward.
All depends on what type of trading you are doing, you can use the same indicators on a longer term chart for longer term trading. There are some here using a weekly Gsat chart rather than a daily, or you could adjust the period to a monthly ,and use the same indicators for a longer look out. Generally the Sto may last a few days where the Macd maybe several weeks on a daily chart, but used together they may help refine entry.
Gsat mid-May through mid-June shows the ADX moving upward with its green DI+ positive indicator to show a sustained up move after the positive macd cross.
In June/july the $indu example shows a flat adx and pps not moving. In Oct the ADX moves up with DI- negative(red adx line) for a two week down move. The end of Oct shows the ADX moving upward with its DI+ positive indicator(green adx line) for a few weeks of rising pps.
