Changing Optimization Values

 
Hi, I can't seem to change any of the optimization values in strategy testers - any ideas why that might be?
Cheers
 
Hmmm,
Are the *.mq4 & *ex4 file attributes set to 'Read Only'?
Can you do a simple back test as opposed to doing the optimization?
Are you able to start and open up the Editor (F4) and then run the Compiler (F5) on the EA or other EAs?
If the EA won't run at all it either has errors in it that the editor (F4) and compiler (F5 once in the editor) pick up on OR even if the compiler doesn't pick up any errors, you may have logic errors, inoperable file structures that won't run.
Can you compile other MQL EAs in the Editor and then change to external variables in the strategy tester and change the settings and then (start to) do an optimization run on them. If so then it is problems such as referred to above is with the specific EA that is currently inoperable.
