Alpaca Cancelling Stops/Trailing Stops

hey guys does the IsSuccessful boolean for checking cancelled orders in live trading work with Alpaca? Just discovered they still don't support trailling stops so have had to implement my own. Planning to just do a check every (minute) bar to see if the security has reached a new high since a position was opened, but has anyone else produced a workaround for this? 

I'm guessing the problem with myt current implementation is I need the algo to wait for a confirmed cancellation from the Alpaca servers before placing a new stop order, otherwise I'm getting an error. 

Reference documentation and error log below:https://www.quantconnect.com/docs/algorithm-reference/trading-and-orders

# Create an order and save its ticket
ticket = self.LimitOrder("SPY", 100, 221.05, False, "SPY Trade to Cancel")# Tag order later
response = ticket.Cancel("Canceled SPY Trade")# Use order response object to read status
if response.IsSuccessful:
self.Debug("Order successfully canceled")

On closer review of my live trading logs, I am still getting the same 'insufficient qty' error, even after implementing a 'IsSuccess' check below:

def OnData(self, data):
# vars for checking stop loss quantities
longQ = -self.Portfolio[self.symbolLong].Quantity
shortQ = -self.Portfolio[self.symbolShort].Quantity


# Update trailling stop on still-open overnight long
if self.OrderIsPlaced(self.symbolLong,longQ) and self.Securities[self.symbolLong].Close > self.longPriceHigh:
self.longPriceHigh = self.Securities[self.symbolLong].Close
self.alpacaTrail(self.symbolLong,self.longStpMktTkt)

# Update trailling stop on intraday short
if self.OrderIsPlaced(self.symbolShort,shortQ) and self.Securities[self.symbolShort].Close > self.shortPriceHigh:
# Alpaca trailling stop
self.shortPriceHigh = self.Securities[self.symbolShort].Close
self.alpacaTrail(self.symbolShort,self.shortStpMktTkt)

def getStop(self,symbol):
goFlat = self.CalculateOrderQuantity(symbol, 0)
return self.StopMarketOrder(symbol, goFlat, (1 - self.trail) * self.Securities[symbol].Close)

def alpacaTrail(self,symbol,ticket):
#self.Debug(ticket)
# Cancel order and assign its confirmation to a variable
#response = self.Transactions.CancelOpenOrders(symbol)
response = ticket.Cancel()
if response.IsSuccess:
ticket = self.getStop(symbol)
