Economic Calendar Events

This indicator provides an overlay of Events on the main chart, where each Event is visually represented by a Label and vertical Line, placed at the specified time interval for each Event.

Events are defined by user data as an input string on the settings widget panel for the indicator. The event data is a string (semicolon delimited) whose grammar is a representation of a collection of Event records, where each Event record is a comma-separated list of fields, which correspond to:

• The name of the event.
  
• The symbol or ticker to which the Event applies (or `*` if it should apply to all ticklers).
  
• The timezone and then the year, month, day, hour, and minute of the event, respectively.
  

Each Event record is separated by the semicolon ";" character.

As an example, assume `evantData` is the string:

"SVB,*,UTC,2023,03,10,00,00;US CPI,*,UTC,2023,04,12,08,30;ETH Shanghai,ETHUSD,UTC,2023,04,12,08,30" 

In the above case, there are 4 Events defined, three of which apply to all tickers and one applies only to ETHUSD, as follows:

• The first event is named SVB and applies to all tickers at UTC time on March 10, 2023 at 12:00:00.
  
• The second event is named US CPI and applies to all tickers at UTC time on April 12, 2023 at 08:30:00.
  
• The third event is named ETH Shanghai and applies to the ETHUSD ticker at UTC time on April 12, 2023 at 08:30:00.
  
• The fourth event is named FOMC Rates and applies to all tickers at UTC time on May 3, 2023 at 14:00:00.
  

The following is a BNF for defining event data:

market-events ::= event-record | event-record ";" market-events
event-record ::= event-name "," ticker ”,” event-timezone "," event-time
event-name ::= string
event-time>::= year "," month "," day "," hour "," minute
event-timezone ::= string
ticker ::= "*" | string
string ::= [A-z0-9]+
year ::= [0-9]{4}
month ::= [0-9]{2}
day ::= [0-9]{2}
hour ::= [0-9]{2}
minute ::= [0-9]{2}

Changes as follows:

• Resolved issue with future events disappearing when a new bar is started and the events have already been drawn.

Changes as follows:

• Expanded event grammar to support partial matching and matching on multiple tickers. For example `ETH*:*BTC*` paints the event on any chart starting either with `ETH` or containing `BTC`
