Does one trading strategy applies to one pair or multiple pairs?

[Sergey Golubev]

It depends on trading strategy about how it was created. Basicly - one pair. But the developer may extent it to many pairs based on futher research for example.

agree. but for other pairs, does the developer change the code or just parameters.

If it just parameters then the trading strategy fits multiple pair 

[Tonny Obare]

It depends since the founder may have discovered the strategy based on the behaviour of only one pair.

It depends if the strategy is dynamic or static rules.
