Looking at the their "system" as a whole, I see "super trend, I see Fib lines, I see bands.
For the bottom, I see "BBMACD" and trend dots.
All of which, you know you have super trend somewhere on your PCs. You also have Fib levels/lines from ARC_Neuro. You can certainly use any types of bands. One comes to mind, the Magical TMA Bands or NonlagMA Bands from NinzaCo. The BBMACD can be used from many free sources. One comes to mind, the one from TDU.
Then the trend dots. Oh boy, there are so many free ones out there. Certainly, you can use one from SMM dots.👌
Finally, we all have Renko bars. No biggies here.
Signals? Plenty. Try one from RightLineTrading, the RLMIPSignalA, or the QuantumTradeStream_AI Signals, TOP_Hedge_Fund Trend Signals and many many more, even ones from Ninza stuff.😁
