Gross FNO PNL for the day

General
1

can you please share the code to get gross PNL for options.

Tried this :

def check_pnl():
    url = "https://api.upstox.com/v2/portfolio/short-term-positions"
    payload = {}
    headers = {
        'Accept': 'application/json',
        'Authorization': f'Bearer {your_access_token}'
    }
    response = requests.request("GET", url, headers=headers, data=payload)
    print(response.text)


check_pnl()

Output :
{"status":"success","data":[]}

there is nothing inside data. I’m trying to code the PNL check before executing the trade, if PNL<max day loss then not to execute new order, so I need 0 when no trades done.
