Can you give me a good condition indicating an imminent trend reversal in either direction?Thank you.

I can't help you create a Condition for "an imminent trend reversal in either direction".
For us to help you create a Condition, you would need to provide an unambiguous objective definition or description of what is actually happening now that you wish to identify, not of what might or might not happen in the future.

For me a trend lasts at least three weeks. An indication of reversal might be three consecutive days of price going in opposite direction: three weeks price increase may be followed by three days down move; vice versa three weeks price decline followed by three consecutive days up.
Can you write a condition for these sequences?
Thank you

You haven't defined what constitutes a trend, but I'll use a negative Linear Regression Slope over 15-Bars with the current Price being below the Price of the start of the Linear Regression as well as the working definition of a downtrend (with an uptrend being the reverse).
Chances are, this isn't what you see as a trend, but that's the hazard of using subjective terms. We can always refine the definition later.
You can just Copy the following RealCode from the forums and Paste it directly onto the Chart in StockFinder to create the RealCode Condition, but you will need to right-click on the Condition and select Edit to change both the Price Rate of Change (% ) Period and Lin Reg Slope Period to 15.
