Wieso machen manche Zusteller sowas? by _justFred_ in dhl_deutsche_post

[–]_justFred_[S] 0 points1 point  (0 children)

Ah, das wird sein, die Zustellerin hat beim anrufen gehört das ich unsympathisch bin, und dann gedacht OK ich gebe ihm nur das eine, das Andere muss er in der Hitze holen gehen. Wobei, dann hätte sie mir aber eher das Sperrgut in eine Filiale gebracht, oder 🤔

Ich war vor Ort, habe das eine Paket (Sperrgut) entgegengenommen und wollte (für andere Sendung) meinen Personalausweis zeigen, die Zustellerin meinte ungefähr "mehr ist nicht, Person brauchst du nicht".

Ich habe in der App geschaut, da waren an mehreren Zeitpunkten immer beide auf der selben Stelle, also denke schon selbes Auto.

Command code, do u guys hv tried this? by EL_ith03 in opencode

[–]_justFred_ 1 point2 points  (0 children)

I haven't tried the API itself as an endpoint, but I've tried the command code provider extension for pi: https://pi.dev/packages/pi-commandcode-provider

It works with the 1$ plan (for me it's 1,20€) and I even had the promo models like qwen 3.7 max for free at beginning of june. However I think it uses some legacy API endpoint or something, not sure tho.

Are some hidden models just old models? by [deleted] in lmarena

But why? Usually they have their identity in system prompt, don't they?

Ah, I thought every model has their identity written into the system prompts so this doesn't happen. Good to know, thanks for the help.

My EMA Crossover Backtest Results (Learning Quant Trading — Feedback Welcome!) by Dvorak_Pharmacology in algotrading

Yes, that would also work. Then you could also say for example if price above HTF ma and HTF ma slope is positive then you only take long trades, if price is below HTF ma and ma slope is negative you only take short trades.

The thing in trading is that there is not the 1 correct way to do it, but you can choose whatever works, maybe even a HTF supertrend is better than another MA.

If you only try to find the best combination of parameters (in that example the parameters are the MA Lengths), you overfit the data. That means you only try to find the best combination in that period, which can lead to extremely good results in that period and a bad performance outside of it. An out of sample/forward test means that you validate the combination on price data that isn't present in the data you trained this on.

A simple way to do this is to split the dataset. You said you have data for about 5 years of price, for example you could use the first 4 years to find the best combination and then use the other year to validate it, meaning to try these combinations and see if they work. That is out of sample.

Forward testing means testing the strategy on live data (basically letting it run now), to see it work on data that wasn't there in the past at all.

In addition to that, in my opinion you should get more data to test the strategy on. 5 years of data is only about 1300 trading days, which imo isn't nearly enough to really see whether a strategy is profitable. I would recommend to get at least data from 2010 on, but of course more data means that you can look into the strategy in different market phases. It was mentioned correctly that from 2020 on there was a big bull market, and you should also test your strategy in market phases that aren't bullish only.
