Roger Posted April 10, 2021 Report Share Posted April 10, 2021 Hello, How many ticker symbols can I put into the scanner before it affects performance speed? Is 2500 companies too many? Thanks. Quote Link to comment Share on other sites More sharing options...
Mike Medved Posted April 10, 2021 Report Share Posted April 10, 2021 It depends on your computer, really. 2500 - that's more than the max # of simultaneous RT symbols allowed by most sources, so that would be a natural limit. The scan itself (once it initializes) only works on incoming data, so it really should not be THAT CPU-intensive. Quote Link to comment Share on other sites More sharing options...
wilburpost2 Posted April 12, 2021 Report Share Posted April 12, 2021 It's not about the number of symbols, it's more like what you want the scanner to do. You can have a fairly involved Paint Bar of hundreds of lines of code, but if it only has to look back a day or two it will run faster than a simple Paint Bar that needs to look back 30 days because you want to compute a 30 day moving average. Think about an active symbol like SPY, that's a lot of trades over 30 days that MT has to digest. When the scanner starts MT has to backfill any missing data, once again, 30 days takes a lot longer than 2 or 3. Even with what I just detailed, the difference between fast or slow, or high or low CPU can be hard to see. MT gobbles up ticks and processes them very quickly. Something like a quad core or higher CPU and SSD probably will not have a problem. My CPU load from MT is <10%. Quote Link to comment Share on other sites More sharing options...
