How To Delete TradeStation’s Symbol Data Cache
Refreshing TradeStation’s data cache can solve many issues when running strategies. To delete TS’s data cache, remove the following folder:
C:\Users\[your user name]\Documents\TradeStation 10.0\CAL\Cache
where [your user name] is the login you use for Windows.
TS will download new symbol data the next time that you run MultiWalk, create a chart, or run a strategy.
