Tags not working with StopMarketOrder in python by Noah Chasek-Macfoy

Playing around with things I have found I can add tags with the MarketOrder constructor using the syntax self.MarketOrder(Symbol symbol, Decimal quantity, DateTime time, String tag) with each parameter as a positional argument and all parameters stated. The equivelant does not work for me with StopMarketOrder.

I couldn't attach the failed backtest, so I commented the failed StopMarketOrder tag attempt. The error it gives is "Runtime Error: Trying to dynamically access a method that does not exist throws a TypeError exception. To prevent the exception, ensure each parameter type matches those required by the StopMarketOrder method. Please checkout the API documentation. at OnData in main.py:line 78 TypeError : No method matches given arguments for StopMarketOrder'

the docu says:

https://www.quantconnect.com/docs/algorithm-reference/trading-and-orders

StopMarketOrder(Symbol symbol, decimal quantity, decimal stopPrice, string tag="")
Submit a market order when the stop price is reached.

did you try without the time parameter?

please write QC the link where you got the old info from or post it here if the tag works correctly.

Sadly, already tried the tag="<string.>" without the time syntax, that doesn't work either... :(

Here are the two doc pages I got the initial idea from. The MarketOrder syntax does work for me.

StopMarketOrder:

self.stopLoss = self.StopMarketOrder(self.future.Symbol, -1.0, data[self.future.Symbol].Price * 0.999, "Stop Loss")

should work

Ahh, thank you! That works. I don't know how I didn't try that. I guess I thought I had tried it because that syntax doesn't work for MarketOrder.
