BEST INDICATOR FOR TLT: When to build positions

We have here a chart of a TLT with a comparison line of the ZN1!/ZB1!. What I have found is that when the ZN1!/ZB1! ratio hits a resistance level, TLT is also nearing it's bottom. I encourage you to look at the ZN1!/ZB1! separately. Recently, TLT has reversed with strength to the upside once these resistance levels are in range.
