It has nothing to do with ignorance. From your 1st post:
@tomas said in Unable to get indicators to work:
I simply get an error on every indicator I try to use saying the following: Module 'backtrader' has no 'sma' memberpylint(no-member)
That's not an error when executing the code. Your IDE is telling you that scanning the module backtrader didn't find something called sma. Actually and given the dynamic nature of Python and the introduction in Python 3.7 of Python of module level __getattr__, that message may actually mean absolutely nothing.
There is no real error if you haven't executed the code. In this particular case, the message was right on spot, sma is not part of the main backtrader module.
In any case, your initial code
@tomas said in Unable to get indicators to work:
def __init__(self):
self.startcash = self.broker.getvalue()
self.sma = bt.sma(self.data.close, period=15)
Now, if one looks at the quickstart guide you will find code like this:
# Add a MovingAverageSimple indicator
self.sma = bt.indicators.SimpleMovingAverage(self.datas[0], period=self.params.maperiod)
which makes it obvious that you didn't go through the Quickstart guide.
Your actual problem is not ignorance or being in the works of porting something from Pinescript. The problem as pointed out above is that you want to start with a high bar and are failing to be able go over it. See, the culprit is quite clear
@tomas said in Unable to get indicators to work:
# Activate optimization
StrategyOptimizationEnabled = False
#Add our strategy
if StrategyOptimizationEnabled == True:
cerebro.optstrategy(TestStrategy, maperiod=range(14,21))
If you optimize (which you are not doing), you add a strategy to Cerebro.
Where do you actually add a strategy to cerebro if you are not optimizing?
Ok, I will answer it: you don't. And if you don't, no indicator can be plotted, because you are actually not instantiating any indicator. As a matter of fact, no strategy code is executing whatsoever. That would have been the 1st logical step, having a script which works without optimization, but that part is obviously missing.
My very sincere advice (you may fully ignore it, consider me arrogant and swear if you wish)
Start with something very small and build up from there. If you cannot get to instantiate a Strategy, you are, in my very humble opinion, far away from needing to play with optimization, which in almost no instance will be of real help.
@ab_trader was very kind to offer you a working script with your indicators. I would suggest you use as the initial building block of a larger strategy.
