Learning Web Development (5)

C# Development, Learning web development
So now I dove a bit into the Gekko docs and it seems fairly simple to create a strategy. This is the thing that outputs the trading advice to Gekko. The tutorials I used are: https://www.youtube.com/watch?v=6-74ZhrG0BE&t=1456s and https://gekko.wizb.it/docs/strategies/creating_a_strategy.html My strategy looks like this (just outputting some trivial things like in the youtube demo): The JavaScript function from the strategy.. The output Gekko can make use of strategies using all kinds of algorithms, but I don't want that. I want to decide each day if I want to buy or sell on a specific input.

SAP PowerDesigner, Tools
  Last week I ran into an issue when creating a stored procedure in a SAP PowerDesigner Physical Data Model. After creating the stored procedure and viewing it in the preview window I noticed something was looking odd: the create procedure statement was showing a pair of empty brackets after the procedure name. Empty brackets in a create proc statement? After running the create statement in SSMS, SQL Server confirmed my suspicion by throwing a syntax error: SQL Says No Next, I investigated the stored procedure body in the editor and found that apparently, PowerDesigner's default SQL Server template for stored procedures features a pair of brackets around the stored procedure parameters. Procedure parameters parameter, enclosed by brackets.. Of course, I tried manually deleting them but this was no use…
