Getting value from custom indicator

[pypl]

Hi Everyone,
I am new to ToS script and I need your help with quite straight forward issue.
I build a custom indicator named H_Range_OC (range of open and close) with only 1 parameter of length.
I want to create a new indicator that return arrow when Close above Range_OC of yesterday and this is what I don't know how to do.
Thanks a lot for your help.
Harry

input length = 15;
plot breakup = if close > H_range_OC(length) then high;
breakup.SetPaintingStrategy(PaintingStrategy.ARROW_UP);

Just in case you need, below is the H_Range_OC. It is quite 'new-bee' script.

input length=15;

def HO = Highest(open, length);
def HC = Highest(close, length);
def LO = Lowest(open, length);
def LC = Lowest(close, length);

plot upper = Max(Max(Max(HO,HC),LO),LC);
plot lower = Min(Min(Min(HO,HC),LO),LC);

Custom studies can't be referenced, so you have to put it all in one study.

input length=15;



def HO = Highest(open, length);

def HC = Highest(close, length);

def LO = Lowest(open, length);

def LC = Lowest(close, length);



plot upper = Max(Max(Max(HO,HC),LO),LC);

plot lower = Min(Min(Min(HO,HC),LO),LC);



plot breakup = if close > upper[1] then high;

breakup.SetPaintingStrategy(PaintingStrategy.ARROW_UP);

This should work, but I'm typing from my phone, so I cannot test it.
