Requests too many securities at PineScript

问题

I am trying to make this script by adding all Binance pairs which are over 250 pairs but I am getting this message: "Script requests too many securities: 48. The limit is 40"

is there any idea to add all Binance pairs? I found this solution but I didn't know how to use it on my code this the solution link: https://kodify.net/tradingview/errors/request-too-many-securities/ and here is my sample code :

//@version=4
study("Custom Screener", overlay = false)
customFunc() => close > open

s1  = security('BTCUSD',  '1', customFunc())

scr_label = 'Screener: \n##########\n'

scr_label := s1  ? scr_label + 'BTCUSD\n'  : scr_label

lab_l = label.new(
      bar_index, 0, scr_label, 
      color=color.gray, 
      textcolor=color.black, 
      style =  label.style_labeldown,
      yloc = yloc.price)

label.delete(lab_l[1])

plot(0, transp = 100)
