Fixed a bug in BB calculation.
Never forget the rockstar here is the Oscillator, that itself bounces between two bands and a basis. Get confident with it!
Though applying BB on it could help spotting more reliable setups, always check price action and look for divergencies.
What works well today maybe won’t tomorrow, so you must keep playing whit settings that fits your needs.
Last but not least consider that when a band steps too much away from +100 -100 levels it wouldn't be a reliable setup.
