Those are my methods. I don't use , SAR , moving averages, stochastics, any of it. My brother is a pro and made millions and he doesn't use them either. He uses angles and a method which he never totally showed me.
If you study my chart on ellipses, there are usually several shallow that they run on.
Anyway this is the daily. I don't even say my guess is right. It's basically an arc swing and an intersection with another circle or arc that was consistent.
As for the 15 minute or 30 minute, for quick speed stuff I just use an acceleration angle and a polyline. The attribute of most stocks the majority of the time is they INCREASE speed as they approach their TOPS or BOTTOMS. Sometimes they lay off more shallow, but most of the time it's an increasing curve.
1. Find the acceleration angle for the chart. They always repeat
2. Follow the edge of the move your on...but watch for the initial sidestep move (it's a shakeout move) to disillusion investors from getting in at the very bottom of a long move up or a good move down.
3. Set a limit angle with that polyline curve approximation. Whatever looks reasonable. I backtest my ideas on charts to see what works best.
Sorry for being long winded but I wouldn't want to mislead you on your short term chart
DanV is a mod here. He would probably give you a quick answer.
