How to get the number of bars in a day in pine script in tradingview?

Question

I'm trying to plot the 9/50/180 day SMA regardless of the timeframe period.

If you're looking at the candles in 1D, 4h, 3h, 15m, .. I just want to see the 9/50/.. day SMA.

If I could calculate the number of bars in a day, I could take the SMA over a 9 * #numberOfCandlesInDay length.

I could define a numberOfMinutes per syminfo.prefix (lots of work) and then calculate the number of bars based on timeframe.multiplier, but that is a hassle and prone to error.

Any tips?

Answer 1

Why not use security() ? This uses our f_secureSecurity() wrapper function so that you avoid repainting:

//@version=4
study("", "MAs", true)
f_secureSecurity(_symbol, _res, _src) => security(_symbol, _res, _src[1], lookahead = barmerge.lookahead_on)
smaD9   = f_secureSecurity(syminfo.tickerid, "D", sma(close, 9))
smaD50  = f_secureSecurity(syminfo.tickerid, "D", sma(close, 50))
smaD180 = f_secureSecurity(syminfo.tickerid, "D", sma(close, 180))
plot(smaD9  )
plot(smaD50 )
plot(smaD180)

Another option is to use a ready-made indie like this one:
