Unable to place order in NIFTY 50

error message in the attachment

Hi @anil_naik ,

The exchange must be ‘NFO’, for limit and trigger price you can specify as 0 instead of false
Refer the below code:

 orderid1 = tsl.order_placement('NIFTY 08 MAY 25000 CALL','NFO', 75, 0, 0, 'MARKET', 'BUY', 'CNC')
