Hi Miguel,

you can only go candle by candle if you are using the Open Prices Only testing model by pressing F12 but I don’t think anyone would recommend to use Open Prices only for testing.

In other testing models you can also use F12 ta advance tick by tick, Greg kindly shared his method in this post: http://spheretester.com/support/topic/shortcuts/#post-1905

Other than that I’m afraid it is not possible to advance a candle by a press of a button at the moment.

I hope this helps.

Regards,
Jan
