Require guidance with ShellExecute()

AFL Programming
1

Hello,

I have trying to shoot BUY Orders from amibroker to my Broker using Python. I can place order for single symbol well, but when I use "Name() + EQ" in AFL , it is not working.

I am using ShellExecute() for this and it works for particular Stock if I specifically mention it in AFL as well as Python file, but does not work when using Name()+EQ (When I use NAME(), there is no -EQ so I have to put +EQ, please see codes)

I am attaching my AFL for BUY orders as well as Python (which shoots orders to broker terminal)

Please help me ! I am tryinig to do this all using AI coding I am not a coder. Its all trial and error !
Please guide me on this little problem

AFL for BUY orders

// BuyOrderParamTrigger.afl
SetTradeDelays(0, 0, 0, 0);  // No delays

// Define the trigger parameter
BuyTrigger = ParamTrigger("Place Buy Order", "CLICK TO BUY");

// Buy signal based on trigger
Buy = BuyTrigger;  // Buy when the trigger is clicked
Sell = 0;          // No sell for this test
BuyPrice = Close;  // Buy at close price

SetPositionSize(1, spsShares);  // 1 share

// Get the current chart symbol and append -EQ
Symbol = Name() + "-EQ";  // e.g., "TCS-EQ"

// Execute Python script with the symbol as a parameter
if (LastValue(Buy)) {
    PopupWindow("Sending Buy for: " + Symbol, "Debug", 5);
    ShellExecute("d:\\Python\\python.exe d:\\amibrokme\\place_order.py " + "\"" + Symbol + "\"", "", "");
}

The following is Code for Python filename place_order.py

# place_order.py
import sys
from NorenRestApiPy.NorenApi import NorenApi

class FlatTradeApiPy(NorenApi):
    def __init__(self):
        NorenApi.__init__(self, host='https://piconnect.flattrade.in/PiConnectTP/', websocket='wss://piconnect.flattrade.in/PiConnectWSTp/', eodhost='https://web.flattrade.in/chartApi/getdata/')

def place_buy_order(symbol=None, qty=1):
    # Get symbol from command-line argument if provided
    if len(sys.argv) > 1:
        symbol = sys.argv[1]  # e.g., "TCS-EQ" from AmiBroker
    else:
        symbol = 'RELIANCE-EQ'  # Default
    print("Symbol received:", symbol)  # Debug print
    
    api = FlatTradeApiPy()
    ret = api.set_session(userid='HIDDEN ON PURPOSE', password='HIDDEN ON PURPOSE!', usertoken='HIDDEN ON PURPOSE')
    print("set_session response:", ret)
    if isinstance(ret, dict):
        if ret.get('stat') != 'Ok':
            print("Session failed:", ret)
            return None
    elif isinstance(ret, bool):
        if not ret:
            print("Session failed: Returned False")
            return None
    else:
        print("Unexpected set_session return type:", type(ret), ret)
        return None
    
    order = api.place_order(
        buy_or_sell='B',
        product_type='C',
        exchange='NSE',
        tradingsymbol=symbol,
        quantity=qty,
        discloseqty=0,
        price_type='MKT',
        price=0,
        trigger_price=0,
        retention='DAY',
        remarks='AmiBroker Dynamic Symbol Test',
        act_id='HIDDEN ON PURPOSEEEE'
    )
    return order

if __name__ == "__main__":
    response = place_buy_order()
    print("Order response:", response)

I am trying to use this Broker FLATTRADE and this is their API Documentation page...

Please guide me !

your arguments to ShellExecute() are wrong, and you don't need to enclose symbol in double quotes.
First arg is the executable( ie. also a command )

ShellExecute(
  "d:\\Python\\python.exe",
  "d:\\amibrokme\\place_order.py" + " " + Symbol,
  "",
  1 
);

and consider using just "py" instead of "d:\Python\python.exe"
set py to default python installation
