"No problem with TR, neo.
Excluding #2 &#3 gives the range [abs(H-L)]"

What I am saying is that TR is distorted in real time by gaps from the
previous day. What I am suggesting is that in RT, the first bar of the day
should not be based on TR but on range only. No need for the abs function
when subtracting the L from the H as it will always be positive.
