3 parameters efficient optimization

[Fatafim]

Hello!

Let's say I have a simple triple sma cross strategy (SMA cross + 3rd MA must be above or below the both of the 2 MAs that do the 'cross'). Whereas it is no problem for me to write this strategy for specific values, I'm having troubles with optimizing it, since there are 3 parameters to find instead of 2 as in simple SMA cross. Would anyone be so kind and show a sample code for this kind of problem?

Well just for the sake of the future generations, eventually I managed to hardcode it with just some for loops. However if there's a prebuilt way to do it please post it here as well.
