Having used ICICI's free breeze API, i find the kiteconnect api not so easy to use in some cases.
The first is the ISIN, which may be required to store data against an unchanging and standard id. I see forum posts from 2018 requesting ISIN in instruments API, its still not done. ISIN is available in holdings, but not in open positions, which i feel is lacking.
Also, can't we provide a getISIN(exch,stock) method in the clients ? Internally, we can fetch the instruments at the start and cache them, so that we don't hit the server every time.
The instruments api should also have a filter on instrument type. e.g. only equity.
When fetching historical data with icici breeze, i just use the trading symbol( tho these they have their own) Whereas here, i am first having to lookup the instrument id. Again, if we cache the instruments list on the client, your api could easily do this lookup internally.
Not being able to see MTF holding quantity in another serious issue.
1. The instrument master file doesn't have an ISIN yet. We are working on adding ISIN to the instrument file. 2. For MTF query, please check out the similar discussion here.
