Plots the % difference between price and bull market support band. Since BMSB is two lines, they're simple averaged together. Top 40 tokens according to Coingecko ( minus stable coins) are chosen for the default display. On display all average certain crypto are taken out for limited price history. Calculation of BMSB applied in this indicator follows:
f(x) =>
sec = request.security(x, 'W', close)
math.avg(((sec-ta.sma(sec,20))/ta.sma(sec,20))*100,((sec-ta.ema(sec,21))/ta.ema(sec,21))*100)
f(x) =>
sec = request.security(x, 'W', close)
math.avg(((sec-ta.sma(sec,20))/ta.sma(sec,20))*100,((sec-ta.ema(sec,21))/ta.ema(sec,21))*100)
