alpaca_trade_api.rest.APIError: symbols cannot contains slashes

Python error messages save the best for last. Typically look at the very last line to get an idea of the problem. In this case

alpaca_trade_api.rest.APIError: symbols cannot contains slashes

Check the variable ticker. Does it contain a valid ticker (eg IBM) and no slashes? The following works

ticker = 'IBM'
candlesticks = alpaca_api.get_barset(ticker, ‘minute’, limit=1)

While this generates the error you are seeing

ticker = 'IBM/'
candlesticks = alpaca_api.get_barset(ticker, ‘minute’, limit=1)

Hope that helps.

Prepare Market order

market_order_data = ClosePositionRequest(
symbol= str(symbol.upper()),
percentage = str(100)
#qty = str(1.0)
)

Submit Market order

market_order = trading_client.submit_order(
order_data=market_order_data
)

alpaca.common.exceptions.APIError: {“code”: 40010001,“message”:qty or notional is required"}

Kindly help:
What is the correct syntax for ClosePositionRequest for a specific SYMBOL.
