QQQ/BTCUSD What is one very valuable tool in our trading day?

This combo here has been so beneficial in forecasting where BTC may be trending. QQQ seems to print a trend about 15 minutes ahead of BTC. It works on any TF from 1 MTF scalping to swing and LT trades. This is one thing you must get familiar with having on your screen as it's very accurate and saves so much time. I've made up a BTCUSD+QQQ chart but getting it fine tuned ATM... Maybe someone would like to take a try at that and let us know how it came out?
