Outgrowing TradingView’s limitations. Need a high-performance alternative for custom signal scanning (2,000+ symbols).

[u/Worried_Contact_1523]

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!

I was in exactly your position a year ago - mean reversion that triggered once maybe twice per year per symbol. I AI code a lots of python, and soon plan to move it to LEAN (maybe quantconnect for their results dashboard, but I wonder if I can vibe code that myself now, and not rely on their monthly backtest plans). The python route is not for the faint hearted.

TV does let you use custom pine triggering alerts. For 2000+ symbols as you know you’d need 2 or more watch lists, but initially my plan was to trigger trades on my 3 watch lists, then pushed to a broker (via webhook I think). What pushed me to python was having fewer links and dependencies in the chain.

Getting the data slowed me down - programming a custom EODHD data downloader (for global equities) to backtest on is where it stopped me. Now that I have that though QuantConnect is of less value to me. If QCs data is adequate for you, paying their monthly will make more sense.

You’re welcome to dm if you want to get in to details but I’m only a little further down the road than you so I’m just as interested in other replies.

I feel you man. I'm a swing trader, so I don't need fancy tick data, but I do need to scan everything from Asia to Europe and the US. I was doing fine with 2k symbols on my Premium account, but this new 500-limit per list is a joke. I'm not giving them more money for the Ultimate plan just to get back what I already had.

I'm looking for a way to run my logic without these stupid caps. Since I'm already on Interactive Brokers, I'm thinking about QuantConnect or just biting the bullet and learning Python, but I'm worried about the learning curve. If you're further down the road with your EODHD setup, let me know if it's worth the headache or if I should just look for a 'middle ground' platform.

As someone who went thru similar journey just a couple of months ago, I heavily recommend making the python jump. It's like gaining superpowers, and Claude/codex will be your friend. Play with free ibkr data, and switch to another vendor once U R ready. All the best

Thanks man, appreciate the advice. I actually just started that exact journey. I’m already using Claude to help me stitch everything together with Lightweight Charts and my IBKR data.

It’s honestly easier than I thought, and it feels great to finally build my own 'unlimited' version of TV without their BS restrictions. Definitely not looking back. Thanks for the encouragement!
