larrybf,
I have also been experimenting with a stochastic on the futures. I trade the S&P mini, but have noticed that the Naz futures sometimes seem smoother in its trend, although I haven't done any testing to know for sure.
I have been using ADX to filter for trend. If there is a high ADX, I only take stochastic signals in the direction of the trend and if its low I will consider both sides. However, I don't use this exclusively, usually combining other things to come up with trade entries.
There are several problems I've found with the stochastics which the "experts" always tout. Since its an oscillator, it will keep you out of big trends because it will remain overbought or oversold during these big runs. Also, you get a lot of fake-out signals. You have to be aware of this when you trade it live. If you look at a chart of the S&P or Naz for the day, you will see many beautiful stochastic signals that picked tops and bottoms of the moves that day. This can blind you to the fact that there are a lot of other signals that quickly reversed and went back below or above the signal levels.
If you ever test a stochastic system in a program like TradeStation, you will almost always have a losing system unless you over-optimize it to the data. There are just too many false signals. That is why I started trying to filter for trend. As with any indicator, it can't be used in isolation. I am still trying to find a combination that I am happy with. I admit much of my trading is still discretionary, using the indicators as confirmation tools.
I have always wanted to put my trading into a strictly systematic form, but I've never found a mechanical system that I am confident in.
I've gotten a little off topic from your question, but to try and answer it, I think the stochastic does have value, but you must find ways to filter the signals, as you seem to be doing. So the experts are right, but that doesn't mean it can't be used successfully. I think market dynamics plays an important part, as I've seen some days where it works great and others where it is just terrible.
I would be interested to know how things turn out for you.
