@sfkiwi said in DivideZeroError on some indicators:
Ok but, unlikely as it is, the price stayed stationary for more than 20mins so shouldn't the indicators still be protected from a divide by zero error?
Nobody has claimed nothing about the price or the protection. Only that you said something was broken without posting any code or data. And when the code and data were posted, the error was somewhere else. Hence the need to post something sensible.
class BollingerBandsPct(BollingerBands):
'''
Extends the Bollinger Bands with a Percentage line
'''
lines = ('pctb',)
params = (('safediv', False), ('safezero', 0.0))
plotlines = dict(pctb=dict(_name='%B')) # display the line as %B on chart
def __init__(self):
super(BollingerBandsPct, self).__init__()
if not self.p.safediv:
self.l.pctb = (self.data - self.l.bot) / (self.l.top - self.l.bot)
else:
self.l.pctb = DivByZero(self.data - self.l.bot, self.l.top - self.l.bot, self.p.safezero)
class BollingerBandsPct_SafeDiv(BollingerBandsPct):
params = (('safediv', True),)
That's something you can directly use in your code. There is no need for a fork to do that.
