@admin Thanks, there was some issue with my code. apologies for inconvenience.

Hi @pt4rh3
did you try to close existing position? when i try i it uses quantity as lots but during sell it use it as shares, so during but i have to use 50 (1 lot = 50 shares) and for sell i have to use 1 for quantity

Hi,
I was buying options and found that during buy we provide quantity of shares (lots * lotsize), but when i sell that option (to close the existing position) and provided same quantity not it considered lots not shares.

for example i brought a put option with 50 shares (1 lot = 50 shares) I have to specify qty: 50 in api request and it buy a 1 lot = 50 shares
but when i try to sell that position with qty: 50 in api request now it will create a order to sell 50 lots (it should be 1 lot similar to buy)

Buy payload

{

'tradingsymbol': 'MARUTI26DEC2412100CE', 
'quantity': 50, // this is buying 1 lot (50 shares)
'transactiontype': 'BUY', 
'ordertype': 'MARKET', 
'variety': 'NORMAL', 
'producttype': 'INTRADAY', 
'price': '0',

}

Sell payload

{
'exchange': 'NFO', 
'tradingsymbol': 'MARUTI26DEC2412100CE', 
'quantity': 50,  // this is selling 50 lots (it should be 1 lot = 50 shares)

'ordertype': 'MARKET', 
'variety': 'NORMAL', 
'producttype': 'INTRADAY', 
'price': '0',

}

@Moderator_3 Is there any way to calculate it ? can you explain with an example that would be very helpful for me.

For some stocks i am getting following error, but same is working for some stocks

:BO: Upticks and downticks should be greater than given percentage: Absolute Price :     25.32 Tick Size :507   Allowed range ->[0-100:      1.00]\t[100-500:      1.00]\t[500-1000:      3.00]\t[>1000:      3.00]\t:
