Download Premium fx scalper indicator
Premium FX Scalper displays a histogram under the trading chart. The histogram consists of green and red signal lines. Red signal lines indicate a sell signal and the green ones – buy signal.
We usually enter on a change of color. Meaning if a red line appeared after a series of green lines – we enter with sell. If a green line appeared after a series of red lines – we enter with buy. It might look very simple it terms of design, however the major work has been put into the inner trading algorithms themselves.
These algorithms work in combination to produce high quality laser accurate signals on your charts.

Converts a string to a MQL4 datetime value; mask is used to determine the positions
where the components (year, month, day, hour, minute, second) are within the string.
If delim="", then the position within the mask gives a component's ABSOLUTE position
in the string (delimiter characters in the mask are optional):
str = "23/06/2000 18:05:00"
mask = "DD MM YYYY HH:II:SS"
Otherwise delim may contain any number of delimiting characters, e.g. delim = " /:"
means that a space, slash or colon may be used to separate variable-width components:
str = "23/6/00 18:05:0"
mask = "DD/MM/YYYY HH:II:SS"
Special tokens in the mask:
DD = Day as a 1 or 2 digit value
MM = Month as a 1 or 2 digit value
MMM = Month as a 3 character ID, e.g. Jan, AUG
YY = 2 digit year value (if > 50, assumed to be 19xx; otherwise, assumed to be 20xx)
YYYY = Y2K compliant 4 digit year value
HH = Hours as a 1 or 2 digit value
II = Minutes as a 1 or 2 digit value

d() outputs up to 8 values to the file /EXPERTS/FILES/DEBUG.TXT, appending data to the end of the file
dd() outputs up to 8 values to the file /EXPERTS/FILES/DEBUG.TXT, creating a new file
