// This is the NYSE Advancers - decliners which the SPX pretty much has to follow. The level gives an idea of days move
//  but I follow the direction as when more advance (green) or decline (red) the index tends to track it pretty closely.


// On SPX and correlateds - very useful for intr-day trading (Scalping or 0DTE option trades) but not for higher time fromes at all.

// I left it at 5 minutes timeframe which displays well on any intraday chart. You can change it by changing the "5" in the security
//  function on line 13 to what you want or change it to timeframe.period (no quotes). 5 min displays better on higher i.e. 15min.
