Filter universe with ma or rsi


I've been trying to filter a universe through a moving average and rsi, however, i havent been getting the expected results.

I started with the MA cross example and added an RSI indicator to debug what going on. I'm getting the following information for each symbol when i debug the symbol, fastMA, slowMA, price and rsi.

Ticker = AADR UOFRJAZTL0TH , Fast MA = 36.64 , Slow = 0.0 , Price = 36.64 , RSI =0.0

I'm sure this is a rookie mistake, but i seem to be getting 0 for both the slow moving average and rsi and then the same value for the price and fast moving average.

I've attached the backtest, Any help would be greatly appreciated

hi Jing Wu 

i think that is an old python example because its not working anymore?

this line does not update the slow moving average and rsi only fast sma:

if, value) and self.slow.Update(time, value) and self.rsi.Update(time, value):

doing this everything works fine:

def update(self, time, value):, value)
self.slow.Update(time, value)
self.rsi.Update(time, value)
fast =
slow = self.slow.Current.Value
rsi = self.rsi.Current.Value
self.is_uptrend = fast > slow * self.tolerance

Hi Michael,

Thank you for the comment.

That helps to update the slow and rsi, however, it still gives an unexpected result


Ticker = AFSD VAAHQ09OPU1X , Fast MA = 25.0 , Slow = 25.0 , Price = 25 , RSI =100.0

For all the symbols, rsi = 100 and the fast MA, slow MA and Price are always equal.


I was not very well in math but glenn how did you set the test period?

start and enddate.......i am asking because the resolution is set to daily and you have


is that a 300 day ex. moving average?  :)


Yes, it was meant to be a 300 day moving average. 

I feel very silly, i was testing it on a non-trading day and wondering why i wasnt getting the correct results. I would have still expected the moving averages to have shown correctly though.

Thanks again!


try to warming up so you see the values at start
