How to correctly locate a Buy Online signal

Hi Pete,

I’m trying to write a script for almost online buying but couldn’t locate the buy signal to be on the right bar. It apears on the next bar. The right bar is the one with the dark_green point. Can you explain how do I create an online buying signal?

Thanks a lot!

here is my script:

input Ticks_Above = 0.2;
input Price = close;
input tradeSize = 100;
input LowPrice = Low;

def UpperBolli = BollingerBands(“num dev dn” = -0.382, “num dev up” = 0.382).UpperBand;

# **** Find where 5 consecutive bars apear
def ConsecutiveAbove = if close >= UpperBolli and close[1] >= UpperBolli[1] and close[2] >= UpperBolli[2] and close[3] >= UpperBolli[3] and close[4] >= UpperBolli[4] then 1 else double.naN;

# temp points of Consecutive above
def ConsAbovePoint = if ConsecutiveAbove ==1 then close else double.naN;
plot ConsAbovePlot = ConsAbovePoint;
ConsAbovePlot.SetDefaultColor(Color.cyan);
ConsAbovePlot.SetLineWeight(2);
ConsAbovePlot.setstyle(curve.points);

# **** Define the end bar of the STHP (above the highest Bollinger band)
def STHP_Above_Flag = if (high[2] > UpperBolli[2] and high > UpperBolli and high[1] > UpperBolli[1]) then 1 else 0;

def STHPivot = if (high < high[1] and high[1] > high[2] and STHP_Above_Flag>0) then high[1] else double.naN;

rec Last_STHP = if (!isNan(STHPivot) and close>= UpperBolli and !isNan(ConsecutiveAbove)) then STHPivot else if (isNan(STHPivot) and close>= UpperBolli and !isNan(ConsecutiveAbove)) then Last_STHP[1] else double.naN;

plot Last_STHPPlot = Last_STHP;
Last_STHPPlot.SetDefaultColor(Color.blue);
Last_STHPPlot.SetLineWeight(2);
Last_STHPPlot.setstyle(curve.points);
plot STHPPlot = STHPivot;
STHPPlot.SetDefaultColor(Color.pink);
STHPPlot.SetLineWeight(5);
STHPPlot.setstyle(curve.points);

def STHP_ConsecAbove = if (!isNan(ConsecutiveAbove[1]) and high>=Last_STHP+Ticks_Above and high>UpperBolli) then Last_STHP+Ticks_Above else double.naN;
plot STHP_ConsecAbove_Plot = STHP_ConsecAbove;
STHP_ConsecAbove_Plot.SetDefaultColor(Color.dark_green);
STHP_ConsecAbove_Plot.SetLineWeight(5);
STHP_ConsecAbove_Plot.setstyle(curve.points);

def Buysignal = if (!isNan(ConsecutiveAbove[1]) and high>=Last_STHP+Ticks_Above and high>UpperBolli) then 1 else 0;
