I dont get it, what do you mean by hard or soft? It is upto you to make it hard or soft, if you are using python then use try/except, or in golang if err != nil,,,, and then handle the error. Different languages has different ways to handle the err…
I havent find any kind of delays in websocket(on average two ticks per sec), albeit I am handling ticks in go, but a programming language doesnt going to make websocket slow. As mentioned by @ANL, the problem is at your end.
And you are not entitl…
1) Redirect URL is the URL of your server, where you be redirecting your login flow to your server's URL, where you programmed it to get access token automatically.
If you havent deployed any server, then in my case, I just use google.com and copy…
I suggest instead of using queue, use redis instead where your key would be token id. It also allow to debug the problems of your program more efficiently. If that works, then move to kafka.
You asked such a general question like "How will I recieve sunlight in my home?" But then blaming @sujith for your vagueness instead of explaining it furthur.
You really wanted to ask a question, or just wanted that someone provide you the code an…
I dont think anyone goint to help you in this regard, as mentioned by @sujith, it is against the regulation. Alas, I have just tested it now, and it is working perfectly fine. Most likely, the problem is from your side, and you have to resolve it.
What access_token validity have to do with you logging out from your frontend, until and unless you are invalidating your acess_token.

The validity of access_token is of full day, just store the acces…
I guess you are using Python in backend.
I dont get it, what is the role of the browser after you got request_token and access_token? Why you creating sessions in browser? Are you using selenium? But why you using selenium to automate the tasks, w…
@Vishalahir No one going to spoon feed you, if you dont know programming language, then first learn the basic concepts, there are lots of free tutorials on youtube.
Furthur, the way you asking that API should also turn off execution of manual orde…
What's the actual problem you are facing here, its a simple code, isnt it?
kill_switch = false
if trade_count > 4 and datetime.now().time() > datetime.strptime('9:45','%H:%M').time():
kill_switch = true
if kill_switch == false:

1) If it wasnt legal, Kite never provided buy-sell API in it.
2) And I dont think there would be any problem in giving access of your repositories to your team.
You can call API inside a loop. But be aware, there is a limit that how many orders you can place per sec.
https://kite.trade/docs/connect/v3/exceptions/#api-rate-limit
@ANL I tried GDFL 4 years ago for quite some time, but what I found that placing a order also takes around 400-600 ms on average (this is from around covid), so a buy-sell time is around 1.5 sec , that was deal breaker to me.
In US, brokers provi…
The problem is raised several times, sometimes eveb discrepencies in NSE data happen, might be due to race condition, BSE data is reliable.
But after checking everything, I came to conclusion that right now, kite's socket is most efficient and relia…
You have to deal with this problem on your own, no one able to help you. As I said this is dark area, and you be violating SEBI rules.
It is quite possible, that should be enough hint for you, if you want to move forward. But if you expecting some…
If you are using python, then you have to maintain a list/pandas dataframe(csv) of instrument symbols, in which you want to trade in. And apply a loop, which run each morning that match your instrument symbols with instrument tokens. You can create …
Why you want to use RDP and installing display drivers in VM? Just learn the commands in terminal, in my installed Fedora/Ubuntu,90% of the time I use commands in terminal.
Use SSH client like putty for connecting to your VM. For persistent te…
But you can always dual boot, furthur, if you thinking of trading in microseconds, then you have to dedicate a machine toward it. Trading in microseconds is no joke, otherwise I suggest you to go toward VPS/VMs with linux, be it GCP or AWS.
As oth…
@ANL For production, linux distros, any day.
Even in terms of performance, linux is best. In terms of support, I can give you example, tensorflow gpu support is only for linux distros, and not for windows. All major stable release first happen for…
Nobody is questioning redis or postgres reliablity, performance or robustness. Its about usecase.
https://zerodha.tech/blog/scaling-with-common-sense/
And here Kallash Nadh explaining that what they faced bottlenecks with Databases. If someone th…
@ANL What I have seen, most of the time bottleneck always comes from Databases. I dont ever suggest to use any databases like postgres or nosql when trying to achieve computation in μ-seconds timeframe. Even M.2 drives bottleneck.
In your case if r…
@ANL Redis will always outperform any DB that use physical drive. If you need to store data in physical drive, then first store in RAM, do the computation, store lets say X number of result's iterations in RAM, and then dump it into DB in single go,…
@rohanrg but that will only estimate the buy/sell vol of limit orders, how you estimate the vol for markets orders?
As I understand most of the time, by priority, buy market orders are matched with sell market orders. Yeah, it might work for illiqu…
@rohanrg how you get orderflow of tick or quote level data? As per my knowledge, NSE/BSE dont share such data even at level 4.
Can you please elaborate how you getting it?
@ANL yeah, with python, it will definetely bottleneck, even with async, threading or multiprocessing (I have tried everything), it will start to miss data/bottleneck when getting it from websocket.
And not just 1 or 2 ticks, sometime it will miss f…
@ANL The code needs to be efficient and optimised. Memory and CPU comes later, for my program I am subscribing around 350 instruments, and storing past 3 hours data into RAM, it is not even taking 1 GB of ram.
The execution of my algo is not e…
@ANL yes airtel do provide static IP for home connections, I think at rs 199+gst.
The reason being, previous year I have noticed it, that sometimes during trading day, the public ip changes, and connection drops to websocket.
For jio, I am talki…
@ANL Airtel Xstream fiber.... they are the best for such kind of work. Bandwidth doesnt matter much.
But if possible, do ask for business leased line, if not, airtel do provide static IP for home connections, it provide much more stable connection.…
Which ISP you are using? Even from NCR, I am getting this. And the connection with websocket is quite stable without any connection drops for whole trading day.

This data is created by using go client, and saved it into mongoDB, from there to csv(for display). I have marked the data with black line, where Volume discrepency is occuring(changes in LTP and LTQ occuring but not in Volume). The time is s…
Yeah I have also noticed this several times, where depth,LTP and LTQ changes, that means trade occured since last tick, but volume remain the same. This is conterintutive in some sense.
I guess imo, this is happening due to hard limit set by Zerod…
