Paper or Live Tradng?

Example Code
The following code works for trading other symbols. GEHI specifically cant be traded on my Alpaca paper account.

if (existing_order_flag == 0) and ((100*float(position.unrealized_plpc)) > 21.0):
    try: 
        print("issuing NEW stop loss order for ", position.symbol)
        # Alternatively, you could use trail_percent:
        api.submit_order(
            symbol=position.symbol,
            qty=position.qty,
            side='sell',
            type='trailing_stop',
            trail_percent=1.0,  # stop price will be hwm*0.99
            time_in_force='gtc',
        )
    except: 
        print("    ***ERROR skip: ", position.symbol)
