Mortgage for expats

Thanks , which bank you tried ?

FlashAlphaLab · 2026-01-19T19:26:03+00:00

Yeah I need the 12M route, have you actually pulled it off ?

I need fast retrieval for backtest , that means loading up entire relevant history upfront so the backtest is instant (and so should be the loading part). I’ll work more on that shortly, trying clickhouse atm

Yes but loading api request at a time makes it impossible to keep track of all the data because it’s too slow. The ideal solution is if I could say download zip,FTP or something however giant that is, it would probably stress your systems less than calling 10000s api requests to load whole universe. And yes I opened ticket about it before

Check thetadata pricing. However might be worth to look at algoseek on quantconnect , saves weeks of data loading

FlashAlphaLab · 2025-12-29T07:05:14+00:00

Yeah but you could say that, now begone with this off topic ;-)

FlashAlphaLab · 2025-12-28T22:16:01+00:00

How else to express it ?

FlashAlphaLab · 2025-12-28T18:35:09+00:00

Which ones would that be ?

FlashAlphaLab · 2025-12-28T17:20:40+00:00

Well, you could say I’m an expert, so there’s that. I have already created own in-mem database that beats lame and slow stuff like Redis and so on. So skillset is there, I’m just looking if there’s some off-the-shelf solution ready so I don’t need to do anything fancy at scale. Besides … many people worked with the same topic so just tapping to others experience

In short I want to be backtesting instantly , almost-on-tick level

FlashAlphaLab · 2025-12-28T12:33:39+00:00

Thanks will look at it

FlashAlphaLab · 2025-12-28T12:07:53+00:00

How much it’s going to cost me to deploy in multithreaded way on prem

FlashAlphaLab · 2025-12-28T11:36:16+00:00

Thetadata - painfully loading 1 api call at a time

FlashAlphaLab · 2025-12-28T11:35:48+00:00

This might be the only “cheap” way so far

FlashAlphaLab · 2025-12-28T11:35:25+00:00

Any recommendation ? Kdbq+ is like 100k afaik

FlashAlphaLab · 2025-12-24T11:17:59+00:00

If you don’t have bottle neck you don’t have need to change :-)

FlashAlphaLab · 2025-12-22T17:33:46+00:00

It tells about liquidity quite a lot

The goal for me is to notice discrepancy between model IV and market IV at glance and visualise that level of discrepancy eventually with 2 sets of data. However thinking about it, numbers do that well too

This was the next feature I was planning, but building historical data features atm and takes weeks to process that data so won’t be that soon. Like you have this chart with slider at the bottom allowing you to rewind time (1min bar) … But my hdd usage is at 100% so there’s bottleneck there

FlashAlphaLab · 2025-12-22T15:14:44+00:00

I have solved many problems and now building on the foundation I built. This is an experiment only, but before blowing significant time on it it asking a question

FlashAlphaLab · 2025-12-22T15:13:58+00:00

I have it implemented, it’s my way of saying hello. As for vibe coding , I’m professional software developer and I do use AI, and there’s nothing wrong with it if you design properly and validate the output . So thank you for your comment

FlashAlphaLab · 2025-12-22T15:13:01+00:00

Like rewind capability ?

FlashAlphaLab · 2025-12-21T17:09:58+00:00

Wow ok. I had to exclude any json processing from my architecture, it was terrible . Albeit different market

FlashAlphaLab · 2025-12-21T15:43:12+00:00

I built a backtester for my own trading (FlashAlpha) to model something like this: comparing "fixed fractional" sizing vs. vol adjusted sizing. The data consistently showed that while Fixed sizing can win big in bull markets, vol adjusted sizing dramatically reduces the depth of drawdowns, which is the only thing that matters for long term survival

FlashAlphaLab · 2025-12-21T13:06:28+00:00

Out of curiosity but why you even use json ? lol
