A trading signal app is only as good as what it lets you check. Before I trust one, I look for a few things. A date and timeframe on every signal. An entry and an original stop. A dated log of every stop move. A recorded exit. Losing trades left in. And a clear line between live signals and backtested results. If an app hides any of those, you have no way to tell whether its signals hold up.
Most app pages show you the same three things: a big headline number, screenshots of a few good trades, and a monthly price. None of that tells you what happened after a signal went out. So here's what I look at instead, using a real row from my own public record. If you're new to signals, start with how daily signals work.
What a trading signal app actually does
A signal app watches a list of markets and runs a set of rules on the chart. Then it tells you three things: when the rules say get in, where the idea is wrong, and when to get out. Some send push alerts. Some post to a feed. Some just update a page once a day.
How the signal gets to you matters less than people think. What matters is whether you can follow each signal from the moment it was published to the moment it closed. And whether you can see every change in between.
The 9-point check
| What to look for | Why it matters | Red flag |
|---|---|---|
| 1. A date and timeframe on every signal | You need to know when the call was made and which candle it came from | Signals with no date, or dates that shift |
| 2. Entry and original stop | The original stop is the risk the trade was planned with | Only a target shown, or a "mental stop" |
| 3. Every stop move, with its date | Trailing stops are normal. You need each move to judge the exit | Only the final stop shown |
| 4. The exit and what triggered it | Stop, reversal, or target, you should see which one | Open trades that quietly disappear |
| 5. Losing trades left in | Every rule set loses. A list with no losers has been cleaned up | Screenshots of winners only |
| 6. Live signals kept apart from backtested results | A backtest is run after the fact. A live signal is called before | One blended number for both |
| 7. A chart you can check the levels on | You should be able to find the entry and stop on real candles | Levels that don't line up with any candle |
| 8. A stated daily close for crypto | Crypto trades 24/7, so "the daily candle" needs a defined end | No stated close time |
| 9. Rows that don't change after publishing | If old signals can be edited, the record can't be trusted | Past signals marked "updated" |
The first five are about one signal. The last four are about the whole record. You need both.
Original stop vs. current stop
This is where most apps lose me. They show the stop as it stands today. Or they just put a "stopped out" label at the end. But the stop moves. On a trailing system it might move every day. If all you see is the last one, you can't work out how much the trade risked or why it closed where it did.
Here's a full row from the published list on my record. It's ALGO-USD on a daily previous-day high/low setup:
| Date | What happened | Level |
|---|---|---|
| 2026-10-12 | Long opened | Entry 0.1264 |
| 2026-10-12 | Original stop set | 0.1137 |
| 2026-10-13 | Stop moved up | 0.1163 |
| 2026-10-14 | Stop moved up | 0.1185 |
| 2026-10-15 | Stop moved up | 0.1221 |
| 2026-10-15 | Exit on flip:short | 0.1153 |
Here's the math. I use R, which is the distance from entry to the original stop:
| Step | Math | Value |
|---|---|---|
| Risk (1R) = entry − original stop | 0.1264 − 0.1137 | 0.0127 |
| Move = exit − entry | 0.1153 − 0.1264 | −0.0111 |
| Result = move ÷ risk | −0.0111 ÷ 0.0127 | −0.87R |
Two things stand out. First, it's a loss, and it stays on the page. Second, the exit landed at 0.1153. That's below the last stop of 0.1221. On this setup the exit fires on a daily close, not at an exact price. So a fast drop can carry it past the line. An app that only showed "stopped out at 0.1221" would hide that gap. The full row shows it.
If you want to see why that happens on this setup, I walk through it in the previous-day high/low strategy on daily charts.
Live signals vs. backtested results
These two get mixed together all the time. They shouldn't be.
A backtest runs a set of rules over past data. It's useful for picking which rules to watch on which market. But it's done after the fact, and it's easy to fit rules to data you've already seen. A live signal is called before anyone knows how it ends.
On my record I keep them on separate lists:
| List | What it holds | What it shows | Can it change? |
|---|---|---|---|
| Published | Signals published since Oct 6, 2026 | Entry, original stop, every dated stop move, exit | No. Rows aren't edited after publishing |
| Already stored | Latest closed trades for the current top indicator on each asset | Entry and exit only | Yes. A scorecard rebuild replaces these rows |
The asset pages show backtested results for each indicator. That's where they belong. If an app rolls backtests and live calls into one figure on its front page, ask which one you're looking at. If it can't tell you, that's your answer.
Crypto needs a defined daily close
Stocks have a session that opens and closes. Crypto doesn't. So any app running daily crypto signals has to pick where one day ends.
On my charts, the crypto daily candle closes at 00:00 UTC. That's 7:00 PM Central during daylight saving time (6:00 PM Central after Nov 1). If you check one of my signals on a chart with a different close, the highs and lows can come out a little different from mine. An app that never says which close it uses is leaving you to guess.
What matters less than you'd think
- Alert speed. On a daily chart, a signal that reaches you a few minutes later is the same signal. Speed matters a lot more on 5-minute charts than on daily ones.
- The number of markets. More coins and stocks don't help if you can't check the signals on any of them.
- The price. Free or paid, I ask the same question: can you check what happened after each signal went out?
- Phone app vs. website. A web page you can open on your phone works fine. What you can see matters more than where you see it.
Test any app for two weeks before you trust it
You don't have to take my word for it, or anyone else's. Run this test:
- Pick five signals as they're published. Write down the date, ticker, side, entry, and stop.
- Open each ticker's chart and find the entry and stop on the candles.
- Check back once a day. Note any stop move the app shows, and when it showed it.
- When each trade closes, write down the exit and the reason.
- After two weeks, compare your notes with what the app's record shows for the same five signals.
If anything changed, or a signal is missing, you've learned what you needed to know. For a broader version of this, see how to check whether a signal track record is real.
FAQ
What is a trading signal app?
A trading signal app runs a set of rules on market charts. It tells you when to enter, where the stop goes, and when to exit. It might send alerts, post to a feed, or update a page. The useful ones also keep a record you can check afterward.
Are trading signal apps worth it?
Only if you can check them. Say an app shows the entry, original stop, every stop move, and the exit for each signal, losses included. That gives you something to learn from. One that shows only winners and a headline number gives you nothing to go on.
How can I tell if a signal app's record is real?
Look for dated signals, original stops, every stop move, recorded exits, and losing trades. Then check a few rows against the chart yourself. Rows that never change after publishing are a good sign. Past signals that get "updated" are not.
What's the difference between backtested results and live signals?
Backtested results come from running rules over past data after the fact. Live signals are published before anyone knows the outcome. Both have a place. But they should be shown apart, so you always know which one you're looking at.
Why can a loss be bigger than the stop?
Some setups exit on a daily close instead of an exact price. If price drops through the stop quickly, the close can land well past it. On my record, an ALGO-USD long had its stop at 0.1221 but exited at 0.1153. That was a −0.87R loss.
Do I need a phone app, or is a website enough?
For daily-chart signals, a website is enough. You check once a day after the close, so a few minutes don't change anything. What counts is whether the site shows the full history of each signal.
