Hope you guys can help me out, been trying to debug this for over a week. Im a pretty newbie in Python. Im trying to test a simple algo using the one Forex pair.
Im buying when the RSI is below 20 and the currentbar greater than the previousbar on 15 min timeframe. after taking the lesson on trailing stops i have added a trailing stop but i get the following error. My code is pretty messy so any feedback is more than welcome
Runtime Error: AttributeError : 'NoneType' object has no attribute 'Update'
at OnData in main.py:line 51 :: self.stopMarketTicket.Update(updateFields)
AttributeError : 'NoneType' object has no attribute 'Update' (Open Stacktrace)

Hi Lakith,
This error arises because in the algorithm above, the logic makes it possible for us to call
self.stopMarketTicket.Update(updateFields)before we've created the ticket with
self.stopMarketTicket = self.StopMarketOrder("EURUSD", -5000, 0.9 * self.Securities["EURUSD"].Close)To resolve this, we can change
else:to
elif self.Portfolio["EURUSD"].Invested:See the attached backtest for reference.

Thank Derek. It worked and not getting the error anymore. But my algo does seems to close any trades.
What i had hoped it have programmed was that once the trade has been initiated the intial stop would be placed at 0.9 from the entry and the trailing stop would move up to 0.9 less the last bars close price.
But when i ran the algo it doesnt seem to close any trades and whole backtesting time would run with only one trade triggers.
Thank you,
Lakith

Hi Lakith,
The reason the algorithm above only makes 1 order is because the stop loss is placed too far away from the spread.
See the attached backtest for reference. We change the stop loss placement from 90% of the security price to 98%.
