Hi @nithin@siva , Does tick by tick data provided by NSE (COLO) contains market depth ? also what do they stream ? they stream all the transactions happening in exchange for all the stocks , futures , options ?
It will be great if you guys share some rows of sample data.
The tick data in India is actually pegged to one second but where as in reality a tick is just one single transaction. There could be many transactions in a second but this sort of data is not available to retail traders here in India but widely available everywhere else in the world. Similarly, the lvl2 and lvl3 data are just limit orders that are highly unreliable since they are delayed by 1 second as well.
By the time the one second data filters through the html and eye candy BS you are witnessing a delayed feedback already.
This whole thing is a professionally orchestrated scam designed to give an edge to traders on the floor.
hmm… to get TBT data you need to take a rack at the exchange colo, place your servers there and consume the data. It isn’t just level 3, it is all data. Every trade, order modification, cancellation, essentially every tick change is provided to you. As you can imagine it is a lot of data, and hence you need to have your server on the colo to consume the feed and can’t be streamed on internet or even high capacity leased lines.
Currently you need to either be a broker or exchange empanelled vendor to get space on the exchange colo.
