Query regarding Trailing Stop Loss

Hello,

I have some questions regarding Fyers API V3.

Let's take an example. I want to put a buy order for NSE:BANKNIFTY2441048600CE. I want to buy this only if the LTP is above 355.

1) Is this limit order correct?

data = {

"symbol":"NSE:BANKNIFTY2441048600CE",

"qty":1,

"type":1,

"side":1,

"productType":"INTRADAY",

"limitPrice":355.00,

"stopPrice":0,

"validity":"DAY",

"disclosedQty":0,

"offlineOrder":False }

2) If I put Qty 1 in the above example: I get an error that 1 is not the minimum lot size. Is there any way I can calculate the lot size?

3) I want to put trailing stop loss. Is there any way fyers take trailing stop loss orders?

3.a) If no, there i write a logic in python. What type of order should I put: CO? Can you please give me an example? Let's say i want to put trailing stop loss (LTP - 30). How should I put these orders in the system and keep on modifying them?

Thanks & Regards,

Sudeep
