Find outside bars and inside bars, with various quantities of smaller bars

[halcyonguy]

finding outside bars and inside bars, with various quantities of smaller bars

here are 2 studies for finding, outside bars and inside bars

draws horizontal lines during the range of bars
can pick a minimum quantity of smaller bars
will find smaller x bars, within larger x bar ranges
can pick wicks or body

uses a loop to find the smaller bars, (up to 100)


outside bar
. a larger bar , with smaller bars before it

inside bar
. a larger bar , followed by smaller bars
https://www.newtraderu.com/2021/12/01/inside-candle-pattern/

-------------------------

i was reading another post and part of the rules included finding inside bars and outside bars...
and i got off on a tangent and made these

Can you make it for MTF? Thank you

Hey, @halcyonguy great work on these. Is it possible for you to do the same extensions on the inside bar
