RE: Code 130 May 2018 18:05
Char - The acronym RNS stands for Really Naughty Signal and is believed to come from the period of time when those chaps wearing garish suits on the exchange floor used to signal to each other via puffs of smoke from their pipes, in the same time period, some of them also bought their pet bulls & bears to work with them. Alas, with the introduction of the non smoking laws and the RSPCA, these practices are no longer in action however, the terminology still carries on.
With regard the code 1 - this indicates that the pipe smoker blew instead of sucking therefor causing a single puff of smoke and some hot cinder damage to his coat.
What is of interest is the code 106 today at 16:29:54 - in my opinion these codes indicate the percentage a share will rise on that day, probably.
Good Luck
