building an options strategy that needs delta and IV continuously to make position sizing and adjustment decisions. logic is written and works on historical data but ive hit a wall on the live data side that i didnt see coming.

my broker shows greeks beautifully on the terminal option chain but the API only returns LTP, OI, bid, ask, volume. zero greeks. so to actually run this live im computing them myself with py_vollib, fetching the risk free rate from a separate source, making assumptions about dividend yield, and trying to handle the indian options settlement nuances (cash settled, european style, weekly cycles, the works). its working but its 200+ lines of code for something that should be a field on the tick. and the IV i compute often disagrees with what the terminal shows by a meaningful amount which is awkward when youre placing trades based on it.

what i actually want is a broker API that streams delta, gamma, theta, vega, IV directly on the options chain websocket. ideally calibrated against the same model the exchange or a recognised data vendor uses so the values are internally consistent and i can just trust them instead of running my own calibration loop.

ive started looking at this seriously and the only Indian broker i can find that exposes greeks live via websocket is Nubra trading app. havent tested it long enough to vouch fully for accuracy or update frequency but on paper it removes the entire compute layer im currently maintaining. anyone here actually using greeks from a broker API in production, and if so which one and how trustworthy are the values?

if youre rolling your own, what library are you using and how are you handling the model calibration question? im on py_vollib right now but seriously considering QuantLib for the more nuanced handling. open to a better recommendation.

I'm getting really sick of Benilde restricting five bajillion websites and also having shitty signal. I tried using Proton but it doesn't work, does anyone have a FREE recommendation?

I’m noticing a pretty annoying gap in my Norwegian. Bokmål reading is slowly improving, and I can recognize grammar when I see it, but saying even boring sentences out loud still feels fake. Like I know “jeg dro på butikken i går” is simple, but if I have to produce it quickly my brain starts translating word by word.

I live somewhere with basically zero Norwegian speakers nearby, so I’ve been trying to separate recognition practice from actual speaking practice. Anki helps me retrieve words, Duolingo/Babbel are fine for light structure, and Pimsleur or shadowing NRK clips/podcasts helps my mouth get used to the rhythm. But shadowing doesn’t train answering. Self-talk is private, but there’s no correction. italki is probably best for nuance, especially sounding less stiff, but I can’t schedule/pay for it constantly.

So my current small hack is: while making coffee or walking around the kitchen, I do 5 minutes of shadowing, then 5-10 minutes answering questions out loud. I’ve also been using Issen for 10 minutes of low-pressure speaking because there are no Norwegian speakers near me. Sometimes I use a random prompt, like summarizing this NPR piece in simple Norwegian: https://www.npr.org/2026/05/11/nx-s1-5816161/will-sharpe-white-lotus-amadeus-mozart

The “research” part is not fancy, but the passive vs active vocabulary idea matches my experience: I recognize words days or weeks before I can actually use them naturally. My next problem is sounding less textbook-ish, especially little things like “da/a”, “ass”, and dialect exposure.

Do other people here deliberately split recognition practice and speaking practice? What has helped you sound more natural and less like you’re reading from a course dialogue?

Hello hello, I'm currently auditing my future expenses. I just want to ask how much an MMA term would cost if the only subject they're taking is MMA-OJT (kasama na yung 10k na misc. fees)

Also, if it can also be answered, dadagdag ba sa base tuition (like the usual subjects and lab fees) yung pag take ng PRACPREP?
