SignalStack and TradingView Bridge both start from a TradingView alert. That is where the overlap ends. SignalStack is a cloud service that turns webhooks into broker orders (stocks, futures, forex, and more) and bills you by how many live signals you send. TradingView Bridge is Windows software plus an MT4/MT5 Expert Advisor that executes on the MetaTrader account you already have.
SignalStack public pricing as of September 2026: free (5 live signals/month), then about $27 / $97 / $340 per month for 50 / 250 / 1,000 live signals (promotional first-year discounts come and go). Check signalstack.com/pricing. They list MT5 via supported brokers’ APIs — not “paste an EA into your prop-firm terminal.”
They are not substitutes
| SignalStack | TradingView Bridge | |
|---|---|---|
| Job | Route webhooks to many brokers/exchanges | TradingView → your MT4/MT5 EA |
| Billing | Per live signal / month | $99 / $149 once |
| TradingView webhooks | Required | Not required |
| MT4 | Not the core product (MT5 via listed brokers) | Yes — .ex4 on your terminal |
| Prop firm MT5 | Only if that firm is a supported API broker | Attach the EA to the firm’s terminal |
| US stocks / options | Yes, that’s a main use case | No — MetaTrader only |
| Where the signal goes | Their cloud | Stays on your PC |
When SignalStack is the right tool
- You chart on TradingView and execute at a US stock/futures broker they connect to
- You need one webhook router across several non-MetaTrader accounts
- You fire fewer than five live orders a month (free tier) or you accept per-signal caps
A day-trading FX system that alerts 20 times a day will chew a 50-signal ($27) plan in a few days. That is by design — they sell volume. A local EA does not meter alerts.
When TradingView Bridge is the right tool
- The account lives in MT4 or MT5 (retail or prop)
- You want unlimited alerts on a paid license, not a monthly signal bucket
- You do not want to buy TradingView webhooks
- You need symbol mapping (
GOLD,EURUSDm) on the terminal you already run
