Have you ever wanted to
- draw lines automatically for notes with fore-, or background colour?
- merge multiple note sources into a single one?
- update notes from files regularly?
- update cloud notes with sub-minute intervals?
(Quick intro video is on Youtube)
After adding and enabling the plugin the configuration panel will be shown:
Refresh Interval defines how often the notes sources will be refreshed and the lines redrawn. It can be configured from 5 seconds to 10 minutes. It defines the data collection, so if you have local files, they will be re-read in every interval, if you have cloud resources, they will be fetched and processed on this interval.
Use Background Color decides if the lines on the chart are drawn with the foreground or background colour defined in the note item.
Notes server address is the local address of the server the add-on will create for your instrument. It is a display only field, it will come handy later, when you configure the Cloud Notes column in Bookmap. The number at the end (so called port number) is deduced from the instrument alias (in the example "NQZ21@GF"). If you use the plugin on many different instruments, it should be different on each and every one, if not, please report it below.
CSV Notes is the manager for the list of local CSV files you want to read and merge. There is no limit on the number of files you can read and merge, but the more you have the bigger the impact is on the performance of the add-on. Use the Add Notes Files button to open the local CSV file. When chosen, it will be added to a small list below the button. If you decide to remove it, click on it in the list and click Remove. You can add multiple files here.
Notes URLs section has a text field, where you can paste or type the location of your cloud notes address (URL). Clicking the Add Notes URL button will add it to a list below. If you want to remove a URL from the list, click on it and click the Remove button.
Line width lets you change the thickness of the line on the chart in price terms (not pixels)
After configuring one file and one URL the config looks like:
This configuration will every 10 seconds:
- re-read the file
- re-read the cloud URL
- merge the notes
- draw them to the chart with the fore-, or background color
- refresh the data on the local notes server served on the Notes server address
Add a Cloud Notes column to Bookmap and configure the Notes server address for the source (in the example - as above-, it is http://localhost:8083):
The refresh interval is irrelevant, the data is sent on a way, that it forces the CLN column to be refreshed every 5 seconds. Since it refreshes from a local server (running on your computer), it should not cause any clogs.
An example of the working example is:
If any of the resources (local or cloud) are not available, levels around that trading price will be painted and the error message displayed in the notes:
PS: Please remark, that the Bookmap Cloud Notes do not work in replay mode!
