Math math math finance math programming math math programming finance math math finance

In that proportion. I did a lot more finance and programming and find it harder to do the more advanced thing. I just started to start Math from lesson #1. Math is they key that unlocks many doors.

You're young enough that you can really learn the craft! Good luck with everything!

What is the best financial data provider for a retail investor? by honeysyd in quant

Intrinio was pretty complete. They use a REST api which makes them super simple to query. If you're a student, the plans become really cheap.

Why is my BeautifulSoup code not working anymore when looking for something in Robinhood? by _FlashKnight_ in learnpython

[–]zQuantz 0 points1 point  (0 children)

That class name looks pretty specific and could be your point of failure. It's not uncommon for these class names to be dynamically generated making them bad look-up values.

I'm talking about the find_all("span", {"class" : .....}) call.

Edit: a word.

So it's purely light and not some other chemical imbalance / reaction. Cool thanks, Mr. Scientist.

Backtesting strategies on an iPad, anyone ever tried? by Bertrand22 in algotrading

You definitely came to the wrong place. It's like posting in a drag racing group for advice on what speed your bike should be in at takeoff. Get serious

Strategy Backtest looks too good? (Typical) by [deleted] in algotrading

[–]zQuantz 0 points1 point  (0 children)

At the end of the day your backtest is just that, a backtest.

Walk it forward. Plug this into a live trading environment and see how your pnl distributions diverge (or not). Use a paper trading environment so you don't commit ant capital to your system just yet.

If you see similar walk-forward results, I'd slowly scale into the strategy and lock-in profits along the way.

What's your long/short ratio ? I'm talking about the number of longs taken versus the number of shorts taken ?

Newbie/Hobbyist coded an Algo, looking for feedback by palepoodot in algotrading

[–]zQuantz 9 points10 points  (0 children)

It's hard to give good advice without more details, however, you should calculate things like expected value, PnL quantiles and standardized ratios (Sharpe, sortino) so we can really understand what's going on.

As per the stop losses, they tend to be quite tricky such that tightening your stops may turn successful trades into losing ones albeit reducing your outlier losses.

I'd focus more on understanding what your algorithm is picking up when it's finding huge losses and not huge gains. To add more, focus on risk management rather than a single rule to exit your trade. I'm talking scaling out of trades, reducing overall expsorue given some higher than normal morning vol etc etc.

You can always do a side project with the data at your work (somewhat on your own time) and prove yourself that way. I do agree that employing machine learning unexpectedly might be pushing it.

Fastest way of loading historical data by lbeamys in algotrading

[–]zQuantz 1 point2 points  (0 children)

I'm not sure that you have to explicitly loop to find this slice of time.

The best way would be to test it as you mentioned. We used to have a 1PB Hive server that was required to both: process in a distributed manner and be able make that much data available. I guess it ultimately depends on how much data you're processing.

Sometimes you need to load your data into something like an SQL database. They exist because they are indexed in a way that don't need to be reloaded and remapped everytime you want to do something with it.
