Issue with setting a stop loss price

[bspallholtz]

I am trying to loop through my open positions and set a trailing stop loss price of 10% off the current price.

Here is my code , get_cp: is another function that gets the current price of a given symbol is_buy: is a function that based on several factors determines if a given symbol is still a buy or not

robin_stocks.login(username, password)
for symbol in holdings:
      quantity = float(holdings[symbol]['quantity'])
      quantity = round(quantity, 0)
      quantity = int(quantity)
      current_return = float(holdings[symbol]['percent_change'])
      if current_return < -10:
          cp = get_cp(symbol)
      if is_buy(symbol) is True:
          stopPrice = cp * .9
      else:
          stopPrice = cp * .97
      stopPrice = round(stopPrice, 2)
      print("I would try and set SLP for %s at %f for quantity %i" % ( symbol, stopPrice, quantity))
      order = robin_stocks.orders.order_sell_stop_loss(symbol, quantity, stopPrice, timeInForce='gtc', extendedHours=True)

This is the return I get

I would try and set SLP for KALV at 6.550000 for quantity 5
{'non_field_errors': ['Stop market sell order requested, but price provided.']}

I've also tried these two functions

robin_stocks.orders.order_buy_stop_loss 
robin_stocks.orders.order(symbol, quantity, orderType, trigger, side, limitPrice=None, stopPrice=stopPrice, timeInForce='gtc', extendedHours=False)
