How many pips a day is realistic for scalping

[PTScalper]

Hi guys,

what is your expectation? How many pips a day is realistic outcome for forex scalping strategy?

In my point of view, im happy, once i make at average around 3-5pips, on 80-120 scalps.
So lets say 240 - 600 pips.
Most of the time at beginning i use like positions 0.1lot .. so target profit is: 240 - 600$ a day.
Once i withdraw deposited money i scale more fastly, to positions 1 - 50 lots, there i can expect in best days profits like 300k$+
(It seems to be very big number, but i use exponential money management)
