Does anybody have any recomendations for trading simulators they've used/do use?

Im searching for something that I could use to trade just as I'd do reside, change timeframes, take possitions ect. Although I would like to be able to modify the rate when wanted.

Id rather pay less than more, but it comes down to the quality and simplicity of use in the long run.

Ive used V-hands in the past but its just not good enough for what I need.

Any feedback welcome,

Leon

Ps, I hope its Ok to post this here.
