This simple script was written for studying recurring intraday behaviours of financial instruments. With it, you can highlight up to 13 customizable time ranges on your chart, filling the corresponding background space with colors you prefer. You can then write a note for each range and it will be shown in the optional related table.
The experience shows that every financial instrument has its own personality. With this in mind, the script can be useful to study intraday charts with the purpose of discovering recurring behaviours of specific instruments over a certain time range and under specific circumstances (normal days, earnings days, days with catalysts, etc.) This can help the trader to deeply understand the instrument personality, and therefore also to decide whether to enter or exit the market if its behaviour meets or not his expectations.
Please note that this script only works on minute/hourly charts.
