The german documentation is horrible.. Sometimes I am very confused. Nevertheless, I will be better (thanks to you!) and can help at least in the German forum at some topics.
At the bottom of this post a table is attached. This table includes additional course data, such as the "number of trades". From these M1 data I would like to make an indicator which shows me for example the number of trades of every bar.
The additional course data is from a custom symbol. I have about 200 Custom symbols. Each custom symbol has about 1 000 000 lines. Therefore, I thought that a database would be the smartest solution. Do you agree with that?
Probably. Not sure it's faster than a simple file, it depends.
Anyway, you need to read all at once at the start, then only update with new data.
the inversionNumber is ONLY used for sanity sake so i can see the DB is being updated !
First run
Second run
The Database snippet seems there's a BLOB !
BUT as you can see the values are not being read back
Code below all error checking removed for clarity.
Any help really appreciated !
