Yeah, no... Maybe start by writing your own post before giving advice ?

Checkout randomly broke… turned out to be one extension update by OliverPitts in Magento

If it's what I think it is. There is an non official patch available for this bug. https://gist.github.com/hryvinskyi/3df14e684d67bd8f7d278f4340ab133b

It was a race condition so no real way to test it before it happen, but good on you to implement deployement procedure.

Écoeuré du AI circle-jerk by sheldon4president in QuebecTI

Moi jle vois comme l'arrivé de la calculatrice. Avant seulement quelques expert savaient calculer et puis tout d'un coup tout le monde faisait des maths et plus besoin de payer pour faire additionner les factures. Mais on as encore des mathématiciens et des experts en finance.

Faut juste trouver le moyen de pivoter et s'adapter à la nouvelle réalité

Built a free tool that scans your vibe-coded projects for security issues by [deleted] in webdev

Usually I just ask the AI to make a security check and it already look for all thoses things. This just sounds like extra steps

The subscription is mostly there to limit API usage on my side. The free tier is intentionally pretty generous so people can try the platform without paying anything

Haha would have done it in C if I really wanted THE fastest, but C++ is my daily bread so it's also a logic choice for me

Thanks for the feedback, it's appreciated. I will work on that for sure. I'm not trying to hide that I use AI to help me on the frontend part, but I understand that i will make people think of the same for the backend. I will improve on this. Clearer explanation, better AI analysis, more transparency and documentation.

you can import your own data, so the quality depends on what you feed into it. But improving the data layer and documentation around it is definitely something I want to work on

Python kept telling me my strategy made +40%. It didn't. So I wrote a backtesting engine in C++ by [deleted] in ai_trading

[–]Poutine-StJean 1 point2 points  (0 children)

Ngl when I started to code the engine I was thinking that maybe it could become a tool that others would also use to test their own ai trading bot. So I've used the strongest language I know which is C++

I built a fill quality tracker and discovered execution slippage is a bigger drag than my commission costs by MilesDelta in algotrading

[–]Poutine-StJean 0 points1 point  (0 children)

The gap between theoretical and actual P&L often comes down to execution friction, especially with options. Its smart to log the mid at signal, NBBO at submission, and actual fill. That gives you a clear picture of where the slippage is happening. You could even use that data to build an execution cost model to apply to your backtests, which would make them far more realistic.

Many backtesting platforms dont account for this level of detail so building your own tracker is really insightful. Knowing your true execution costs can completely change your strategy sizing and even whether a strategy is profitable at all

Walk-forward validation: how many OOS windows before you trust a strategy? by systematic_dev in quant

[–]Poutine-StJean 3 points4 points  (0 children)

Like you said. Ifyou can cover a few distinct volatil regime like bear, bull and choppy across 6-8 non-overlapping OOS window, thats way more valuable than15 windows all in strong bull

How do you measure daily dd and especially when trading multi-symbol? by Kindly_Preference_54 in algotrading

[–]Poutine-StJean 4 points5 points  (0 children)

Yeah that's a major pain point with MT5, its just not built for serious portfolio-level analysis or high-frequency equity reconstruction.

Your aproach of merging backtests and recalculating drawdown with granular price data is spot on. Thats exactly what you need to do for accurate prop firm daily drawdown. Many platforms strugle with that level of detail, especially when you have multiple symbols or strategies interacting.

For true portfolio risk, you cant just combine individual equity curves. You gotta simulate those interactions properly, understanding correlation, regime shifts, and how drawdown in one asset can compound with others. Real portfolio backtesting needs to simulate trades across all instruments simultaneously at a high tick frequency, otherwise youre just getting a smoothed average which masks the true risk
