Strategy: different results from 5 to 4 digits

I ask this to who has backtesting strategies experiencies:
I made a automated staretegy that gives great results on 5 digit broker but not on 4 digit one.
Could be reliable?

Thanks.

no one could help me?

I'm not sure if your question "could be reliable?" is quite clear. What exactly are you trying to ask?

I mean that works only with 5 digits, cos it uses fractional pips for open an close order, the gain for every trade is small, and if i use it with 4 digits it dosen't work. If entry and exit are not exactly it could'nt work.
It can have a margin of 1 or 2 micropips and I was wondering if going to live it can be reliably.

Thanks.

No.

Thanks for the confirmation.
