/*
I expanded a little bit On Reinsley's
code (see below) for those that work in 24 Hour markets(e.g. Forex). I left his
code intact: Additions are between ADDED-END markers.
This way one can easily look NOT just at
(1)EOD, but also (2)at the European/London/NY/Tokyo sessions' 1st Hour. Also,
those who use premarket can easily compare today's premarket and first hour
with previous days 1st Hour.

Subject: Re: [amibroker] Retrieving yesterday's daily O/H/L/C during RTH
in an intraday database?
Don't apologize, we all are newbies for about a decade or more...
I am the worst AB pedagogue.
Blue lines are the HHV and the LLV of the first hour. We can't plot them
before the end of the first hour.
Adjust the time to match to your market's hour.
Gold lines are support and resistance with a 2.618 fibo ratio. These
lines have nothing to do whith your problem. It's just a ratio that is
often hit by the future I follow. I read nothing about that, it's just a
personnal research.
Sorry, I don't know what a Macd summation index is. I don't have such a
thing in my AB library.
Best regards
