Hi, great script. It's nice there's a library for Net Liquidity to overlay as an indicator rather than using calculations in the Compare function in TV.
This is how I've used the Net Liquidity in my work
Add to compare the calculation below
FRED:WALCL-(FRED:RRPONTSYD+FRED:WDTGAL)

Few thoughts, the "float val" array is long, I bet there's a way to reduce the array size from 250 lines of code to less than 5. Maybe using the max_bars_back as in

library("NetLiquidityLibrary", overlay = true, max_bars_back = 250)

Again, great script
