You'll need a different stop for the long and the short trades:

Stop = Price + 50*PIP;
enterShort(1,-15*PIP);
enterShort(1,-20*PIP);
enterShort(1,-25*PIP);

Stop = Price - 50*PIP;
enterLong(1,-15*PIP);
enterLong(1,-20*PIP);
enterLong(1,-25*PIP);

Giving only the 50*PIP distance would not work here because it would then be the distance from the entry price, not from the 8 o'clock price.
