For individual stocks, recommend swiching your chart from monthly to weekly while keeping the indicator as is at 13-day.
Ive only tried a handful of large caps so far, but weekly is a much better fit (and is way more useful if it works) than the monthly.
Monthly seems to have worked decently on BTC as well, so maybe the monthly is more accurate for broader indexes while weekly is better for individual, specific assets. Just thinking out loud, dont mind me.
