[Python] ib_async TWS API only first order gets transmitted, remaining orders doesnt show on...

Currently, I have a function that creates 3 orders:

1. Market order to enter the stock
2. Limit order for taking profit
3. Stop order for stop loss

However, on TWS only the first order is shown and auto transmitted to TWS through API. Furthermore, for each instance, only the very first order gets transmitted.

from ib_async import *

ib = IB()
ib.connect('127.0.0.1', 7497, clientId=0)

def place_order(tradeDirection: str, ticker: str, riskSize: float, entryPrice: float, exitPrice: float):
logger.info(f"====== Placing order for {ticker} ======")

positionSize = get_position_size(get_risk(riskSize), entryPrice, exitPrice, tradeDirection)
contract = Stock(ticker, 'SMART', 'USD')

# Parent Market Order
parent_order = MarketOrder(tradeDirection, positionSize)

# Calculate TP and SL
if tradeDirection == "BUY":
takeProfitPrice = entryPrice + 2 * (entryPrice - exitPrice)
stopLossPrice = exitPrice
tp_order = LimitOrder("SELL", positionSize, takeProfitPrice)
sl_order = StopOrder("SELL", positionSize, stopLossPrice)

elif tradeDirection == "SELL":
takeProfitPrice = entryPrice - 2 * (exitPrice - entryPrice)
stopLossPrice = exitPrice
tp_order = LimitOrder("BUY", positionSize, takeProfitPrice)
sl_order = StopOrder("BUY", positionSize, stopLossPrice)


# Place all orders
ib.placeOrder(contract, parent_order)
ib.sleep(0)
ib.placeOrder(contract, tp_order)
ib.sleep(0)
ib.placeOrder(contract, sl_order)

logger.info(f"Main Order placed: {parent_order}")
logger.info(f"TP order placed: {tp_order}")
logger.info(f"SL order placed: {sl_order}")


From the logs, you can see there are 3 orders inside Open Orders, but on TWS only the 1st Market Order gets transmitted and filled.

How can I make all 3 orders be transmitted to TWS?
