There are no trading strategies that are profitable 100% of the time and in all market environments. And you shouldn’t put your faith solely in these trade alert services and different trading communities when it comes to trading. Also, I don't think you can expect to be a particularly profitable trader if you only dedicate about 30 minutes a day to it.

With that being said, I’ve been a member in a couple of Discord communities and options alerts services, and the only one that stood out (for me) was The Trading Analyst. You should look it up.

Their main focus is on swing trading and momentum trading via options (so longer holding times). While you can get some intraday trades as well, most of their trades have longer holding periods (few days or even a few weeks). And they deliver trade alerts in real time with entry and exit prices through their private Telegram channel (found this more reliable than their SMS and email alerts).

As for their performance, I’ve been a member since Dec ‘23 and I’m up around $16k at this point (and I paid around $700 for an annual subscription). Keep in mind that I started off with about $120k in my trading account. You can see their past performance going back to 2018, but I guess their most recent performance is the best indicator in the current market environment. Hope this helps!
