Quote from Synaptic:
This may not seem like good TA but humor me here .....observing the SPX over the last 1-2 years, I notice that using a Full Stochastic setting of say 14,6,6 and watching when the fast line has moved to at least 90 or above, if you sell a FOTM bear call spread when the slow line crosses the fast line, you end up with some very safe trades.
Whats important to remember when using TA is that overbought can stay overbought and oversold can stay oversold for a while before it actually turns. You can see examples on any chart you look at. If you are going to rely on TA alone, you better make sure you live to trade another day when the exception happens.
What you said is true, opening call positions within 10 points of the 3 month high and put positions within 10 points of the 3 month low would have been very profitable over the past 2 years.
