Gap Trader

• Plot the most recent 20 gaps based on custom session info.
  
• The session can be customized with a start time and an end time.
  
• The previous open, high, low, close are only from the price during the session specified.
  
• A gap line will stop printing the moment the gap is filled.
  
• For CME futures, the session must be offset by one hour for Central time. I use the official cash close of 16:15 EST (yes, not 16:00) as this is the TRUE close when options go offline. Every day CME futures take a break between 16:15 - 16:30 EST for settlement, and then again from 17:00 - 18:00 EST.
  
• To offset CME futures you must subtract an hour, the official NYSE hours for futures: 0830-1515, this translates to 9:30 AM EST - 4:15 PM EST.

Versionsinformation:

• Added timezone feature. Use the timezone to match the session window. For example, when using the cash session of the NYSE as 0930-1600, the correct timezone would be GMT-4. However, if your Trading View settings are set for GMT+0 for London time, then the session window should be set to 1430-2100. The timezone feature is used to specify the local time with respect to the session window.
