@tradernoob I had used the TrueData Velocity feature but not the API service, but it is widely used and I am not sure about the latency.

@tradernoob I have read all of your threads before in Q&A. If you are a pure seconds based trader and want to scale up, I think the current issues will kill your strategy.

If there is a few millisecond discrepancy in the timestamp between the current and exchange timestamps, it is acceptable and normal for retailer trading.
Please include milliseconds for all timestamps, as now…
1 second delay will not be a big issue for traders with strategies more than 10 minutes, but this delay will kill traders who trade in seconds.
@tradernoob I am wondering why no one raised this as a serious issue, though a lot of people use the Kit…

@themohammedfaisal Yes Agreed. LTT will vary depending on the instrument's liquidity. The current delay is beyond that; the current time and exchange timestamp should match, right? I have checked many times and tested with simple dummy code for time…
Any help would be appreciated. created this thread yesterday. I have been paying KiteConnect for years. I can't take a trade due to this issue.
tick time mismatch:
some ticks have same time:
Today I noticed the same issue. I just added up the exchange timestamp, and it is 1 second below the ticks I am receiving. Some ticks show on time; both the current time in my system and the exchange timestamp are equal.
To sum up, I have noticed some instruments time differences are high, like a difference of 5 seconds or more.
Is this definitely because of the last traded time of illiquid or far OTM instruments?
The last traded time will print when there is a las…
Why do you need an independent program to get on_order_update? You can consume the same in either of those existing ws connections.
The entire order handling program is considered a separate program.
Currently, I am running three subscription programs with the on_order_update program. Is this because of legacy reasons? Any exception for on_order_update in future?
Yes. You can use WebSocket to get order updates. It is not like polling using kite.positions()
You can use on_order_update() and it is an event driven asyncrounous call. You will get order updates as updates are out of order. you have to do at your …

Yes. You can unsubscribe the tokens. Try this ws.unsubscribe([tokens])

You have to subscribe tokens using WebSocket
1. Try DB then fetch
2. Try native dictionary then fetch

GTT orders are not considered normal orders, so when you place a GTT order, it will create a trigger ID, not an order ID like placing normal orders. You will only get the order ID when the GTT order gets triggered.

You can check Zerodha's bulletin, as it is clearly mentioned that GTT orders will not trigger.
You can place GTT orders, but it will not trigger, may be the reason it was working fine when placing GTT.

IOC will cancel automatically if it is not matched, but I want to cancel at a specific time. My strategy is to cancel if it reaches a specific time. I am getting the same error if I place a limit order.
This is very personal. Python offers a rich library that is well suited for both machine learning and data analysis. Python is the language that "most people" use for quant trading because of its ease of use. Python can handle practically all the wo…
Deciding the program language is very crucial. Before you go with a programming language, you must decide what kind of strategy you have or what time you want to place orders. If your methodology is for high-speed trading, then I would prefer a comp…

> As I understand from the thread you shared, we can't predict the time it's generating the candle, so the poll historical data API is not good for live trading. (e.g., 10.00.00 a.m. candle forming after 10.01.30 a.m. (10s or 20s dela…
@sujith I agreed. OHLC derived from the last traded price differs from historical data. I would want to hear what you think about this. Can we trust OHLC derived from last_traded because both historical data and derived OHLC differ? suppose volumes…

1. Could you please give some clarity regarding the way you store data in TimescaleDB? Actually, I am storing OHLC data and some other computations every minute for a 1-minute interval. One code has multiple operations beyond just storing…
@MAG What's your opinion of using TimescaleDB over Redis? PostgreSQL DB is storing data on the ROM, not in RAM. TimescaleDB has time series, but Redis also has time series. Redis is using RAM, so efficiency and faster performance are intact in Redis…
@rohanrg Thanks
The timescale is PostgreSQL DB, and I have not used or tested this DB. If you are facing any delay, I would recommend using Redis. It is faster than other DBs to handle high Fz data. But if you have not tested Redis , then it might b…
@rohanrg You stated that you are storing tick data for 650 tokens and then processing OHLC. So, which data storage are you depending on for this process?

@MAG If I change to AWS, then the latency of the ISP will not be an issue, right? If you use native Windows RDP for login, the AWS is delayed. or will the ISP latency kill the user experience while using AWS?
What is your experience on this matter?
@MAG Except for the efficient virtual machine advantage when commuting and the lower latency, I believe AWS is not ideal for me. I checked the pricing of the instance; it is actually head-over for me to keep the subscription. I am still using the de…
