])

print(f"Total Margin Required: {margin['data']['total_margin_required']}")
print(f"SPAN Margin: {margin['data']['span_margin']}")
print(f"Exposure Margin: {margin['data']['exposure_margin']}")

Notes

• Always check available margin before placing option sell orders
• Use splitsize parameter for large orders to avoid freeze quantity limits
• Weekly options expire on Thursday, monthly on last Thursday
• NIFTY lot size is 75, BANKNIFTY is 30
• Use Analyzer mode for paper trading: client.analyzertoggle(mode=True)
