Trading Signal Explained: From Chart Alert to Executed Trade in 2025
A trading signal is simply a trigger—"buy now," "close short," "exit long"—generated by human analysis or an algorithm. When the signal fires, traders decide whether to act manually or let software do it for them. Definitions vary, but Investopedia boils it down to "a trigger for action, either to buy or sell a security, generated by analysis." With 24-hour markets and more than 900 million Telegram users—a favourite channel for real-time alerts—quality signals are more accessible (and noisy) than ever. This guide clarifies the types of trading signals, how to judge their reliability, and a three-step workflow to automate any TradingView alert into a live order on MetaTrader 4 or 5 in under five minutes.
1 | Types of trading signals
| Type | Source | Typical delivery |
|---|---|---|
| Manual / discretionary | Human analyst spots a pattern or news catalyst. | Text message, email, Telegram post. |
| Rule-based algorithm | Technical indicator cross, price breakout, moving-average slope. | Platform pop-up, webhook, push notification. |
| AI-driven model | Machine-learning predicts next candle or detects sentiment shift. | API feed, JSON webhook, bot chat. |
| Copy-trade feed | Mirror a provider's live account automatically. | Broker's social-trading panel or dedicated EA. |
A buy-signal is just one subtype—any predefined condition that prompts a purchase.
2 | What makes a "good" trading signal?
- Clear entry & exit rules – exact price, stop-loss, take-profit or trailing logic.
- Back-tested edge – at least three years of tick data (or 1,000 trades) with stable win-rate and drawdown.
- Timely delivery – latency under one second for fast markets like FX or crypto.
- Transparent performance logs – share every historical trade, not only winners.
- Risk disclosure & sizing – specify lot size or risk-% so followers can scale safely.
Forex-signal systems that skip these basics often fall into the "black-box" trap described by Investopedia.
3 | Top signal delivery channels in 2025
- TradingView Alerts – Webhooks fire the moment your indicator or strategy condition hits.
- Telegram Bots – Huge reach, emoji-rich formatting, and inline buttons for extra context.
- Email / SMS – Still popular for longer-term swing trades where seconds don't matter.
- Broker Push Notifications – MT4/MT5 mobile apps pop up entries and exits instantly.
Why webhooks win for automation: They pass structured JSON, so software can parse symbol, side, and price without guesswork.

5 | Frequently asked questions
Are trading signals legal?
Yes, but providers in many regions must disclose risks and avoid guaranteed-profit claims. Check local regulations.
Can I build my own signals in TradingView without coding?
Absolutely—combine built-in indicators with alert conditions, or tweak a public script's parameters.
How fast do PineXchange signals reach MT4/MT5?
Internal benchmarks show sub-second routing for 95% of alerts; final fill speed depends on your broker's execution.
What's the safest way to test a new signal?
Run it on a demo or small-lot live account first, and log at least 100 trades before scaling.
What happens when my PineXchange trial ends?
Automation pauses, but your settings stay saved. Upgrade on the pricing page to continue trading.
