Just for context, I’m mainly a swing trader in stocks. I’ve never really focused much on forex because I’ve always seen it as very difficult and kind of random in the way it moves. Also, the lack of real volume data makes a huge difference for the way I trade.

Lately though, I’ve been thinking about spending some time building a few EAs and testing some strategies. So I’m wondering if there are actually any profitable bots out there. The first ones I tried years ago were complete garbage, but now with AI I was thinking about creating a few myself just to see if it’s worth it.

What I’d really like to understand is what most profitable systems are actually based on — grid systems, martingale, moving averages, or something else entirely.

I’d really appreciate hearing about your experiences and any advice.

Hey guys,

I’m finally at a breaking point with TradingView. I’m a swing trader and I need to run custom signal logic across massive watchlists (around 2,000+ symbols covering US, EU, and Asia).

TV just nerfed their watchlist limits to 500 per list on my plan, and they want me to pay for the Ultimate tier just to get back the capacity I had before. I’m not doing it.

Since I already use Interactive Brokers as my main broker, I figured it’s time to move my "scanning engine" closer to the source.

My setup/needs:

Scale: Needs to handle custom technical logic on 2,000+ tickers without a "cloud limit" headache.

Logic: I was using Pine Script for things like mean reversion and custom momentum setups.

Alerting: I just need a dashboard or alerts when a setup triggers on one of those 2,000 stocks.

I’ve heard about QuantConnect (integrates with IBKR) or just going the Python/API route, but I’m not a professional dev and I'm worried about the learning curve.

Is anyone here using the IBKR API or a third-party tool (like TrendSpider or MotiveWave) to run this kind of heavy scanning? Or should I just bite the bullet and learn how to use Python with IBKR?

Would love to hear how you guys handle large-scale scanning without relying on TradingView. Thanks!

Hi everyone,

I’ve hit a wall with TradingView. I’ve been using Pine Script to run custom signal logic across multiple watchlists, but their recent decision to cap lists at 500 symbols has effectively broken my workflow. I need to scan at least 2,000+ symbols simultaneously, and TV’s cloud limitations are no longer cutting it.

I’m looking for a platform that offers a TradingView-like experience (clean charts, easy scripting, alerts) but with much more horsepower under the hood for large-scale scanning.

My specific needs:

Heavy Custom Logic: I’m not looking for a basic price/volume screener. I need to run complex, multi-condition scripts (like I did with Pine) that process the entire universe on the fly.

Scale: Must handle 2,000+ tickers without lagging or hitting arbitrary "symbol caps."

Alerting/Dashboard: I need to be notified or see a real-time list when my script triggers a signal on any of those 2,000+ stocks.

What I'm considering:

QuantConnect: I know it's the "gold standard" for algo trading, but how is the UI/UX for someone used to TV’s visual environment? Is the Python/Lean learning curve worth it just for scanning?

TrendSpider: I’ve heard their "Market Scanner" is powerful, but can it handle the same level of script complexity as a dedicated coding environment?

Local/Python Frameworks: I’m open to running things locally if there’s a framework that handles the data pipe and provides a decent UI for visualization.

Has anyone else here "graduated" from Pine Script to something more robust for market-wide scanning? I love the ease of use of TV, but I can’t deal with the constant nerfing of capacity. What’s the best "middle ground" between a retail charting app and a full-blown institutional HFT setup?

Thanks for any suggestions!

Is it normal that with the Premium plan I could create a watchlist with up to 1,000 symbols, and now it’s suddenly limited to 500?

Is anyone else experiencing this with TradingView?

Changing the limits after customers have already paid for a full year is completely unacceptable. I paid for Premium based on the features that were advertised at the time, and reducing those features afterward feels dishonest.
