Hi all!
Actually trying to get the algos' programming logic, so I decided to build a very basic one but unfortunately, no trades are generated which is very frustrating:
Algo's Trading rule: Enter Long on TSLA if RSI > 51 and if RSI < 60. I'm pretty sure to miss something that might be an evidence for you, but I'm totally stuck with this.
I first thought that the RSI indicator wasn't "updated" but even when I write an algo that should trade if the stock's price is > X, it won't place any trades.
Also, if I can get this to work properly, I'll be able to understand who to manage orders, data and indicators, In other words, I would be able to build any strategies so your help would be really appreciated.
Cheers!
import numpy as np
class RSIalgo(QCAlgorithm):
def Initialize(self):
# Define a date range and strating capital for backtest
self.SetStartDate(2018, 6, 24) # Backtest starting date
self.SetEndDate(2018, 8, 24) # Last date = Today
self.SetCash(10000) # Define the initial capital
# Select the stock to trade
self.tesla = self.AddEquity("TSLA", Resolution.Daily)
def OnData(self, data):
# Make the algo work every days
self.Schedule.On(self.DateRules.EveryDay("SPY"))
# Calling the RSI Indicator
self.rsi = self.RSI("TSLA", 14, MovingAverageType.Simple, Resolution.Daily)
# If we are not invest in TSLA and RSI crosses above 30 go long
if not self.Portfolio["TSLA"].Invested:
if self.rsi > 51 and self.rsi < 60:
self.MarketOrder("TSLA", 22)

When I execute this code, I get this error:
Runtime Error: TypeError : Cannot get managed object
at OnData in main.py:line 26
TypeError : Cannot get managed object (Open Stacktrace)

The reason as to why the TypeError occured is because the RelativeStrengthIndex object was being compared to a number. In order to get the value of the indicator, use indicator.Current.Value. The algorithm below has the necessary fix:

Thanks Gurumeher! It is working fine now!
