25-85% gains. 5-10% losses day trading using margin. Sorry if that was shitty wording.

The principal I work off is based around the idea that prices move in waves similar to elliot wave theory. So I get three targets for the 5 waves in any direction. That's oversimplifying it but gives you an idea how I might expect further movements. I haven't figured out the time aspect yet and I'm working on that but the red vertical line in the second chart is a cycle end drawn in March 2021. But I haven't figured the time cycle part out yet. Tried studying hurst cycles and need to go back to it again but found it difficult to gel with.

The green line was drawn mid July once the low price had established itself. It's not formula based but geometry based working off the low. As long as you have a correctly scaled chart it will work most of the time. It was drawn not by connecting lows but with angles, once the chart is scaled correctly. But that's not what I use for price predictions. The lines in the first are all calculated from a 2018 low. If I'd known how I could have drawn them then. The price was much lower than it is now at that point. I can project those lines into the future to infinity. The second chart's horizontal lines are all calculated from specific highs and lows. A combination of both charts will pick out most moves.

I haven't included the ATH or lows on these examples. They just show how well it picked out a move again this week.
