It is important to realize when something just isn't working, no matter how much time or how committed you are to it. If it isn't better than what is already out there, or if it just flat out isn't good, then let it go (to indicator heaven).
For about a month I spent hours each day working on Mike Trend. The goal was to create an indicator that was smooth yet fast, showing long term trends and short term reversals, all-in-one.
In the end, it just wasn't any better than the other more common tools already out there. For instance, a good T3 moving average can identify reversals easily and is quite smooth. And a good bid/ask volume indicator can show you upward and downward pressure of the market to identify long term trends, or you can just watch price itself on a big chart and spot the trend.
What should be learned from this is that you have to be careful in getting caught up with something that just doesn't work.
"Mike Trend" you will be missed, but not forgotten.
