Trading signals: what to look for in a signal service

Guide · approx. 6 min read

Signal services are everywhere – and unfortunately so are dubious providers with unrealistic promises. To help you tell the serious ones from the rest, here are the 7 most important criteria to check before you spend money on signals.

1. Real transparency, not just winners

The most important point: does the provider show its full history – including losing trades? Anyone who only posts winners and hides losses is a red flag. An honest performance overview with winners and losers is a must.

2. Clearly defined trades

A usable signal always contains three things: entry, stop-loss and target. Without a stop-loss it is not a signal, it is a gamble. Without defined risk you cannot size your position.

3. Realistic win rates

Win rates of "95%+" are almost always cherry-picked or based on tiny partial targets. The risk-reward ratio matters more than the raw win rate: even a 50% win rate is profitable if wins are bigger than losses.

4. No profit promises

"Double your account in 30 days" – anyone advertising like that is selling dreams, not signals. Serious providers make no profit promises and clearly state the risk of loss.

5. A method you can follow

Do you understand how the signals are generated? A clear method – such as a rule-based scanner for Wolfe Waves – is more trustworthy than a "secret strategy" no one can explain.

6. Fair, cancellable pricing

Serious services are cancellable monthly and hide no costs. Large one-off payments or long lock-in periods are a bad sign.

7. A free preview

Can you form an opinion before buying? A provider that shows you free sample signals has nothing to hide.

Five questions any provider must be able to answer

1. Are signals published before the outcome? A screenshot after the win proves nothing. Only entry, stop and target shown beforehand can be verified.
2. Are costs included? Spread, commission and slippage eat a serious share of the result, especially with tight stops. Without a cost figure, any statistic is flattering.
3. How is the exit handled? Partial exits and a break-even stop lift the hit rate sharply without improving the result. Without the exit rule, a hit rate says nothing.
4. How many signals are behind the number? At 30 trades it is all chance. It becomes meaningful from a few hundred.
5. Are there losing stretches? Every real curve has bad months. If they are missing, something else is too.

Hit rate or result per trade?

The hit rate is the most advertised and least informative number in the signal business. An example from our own measurements: the cup and handle pattern wins only 38 percent of the time – and is still positive, because the target sits more than twice as far away as the stop. The double top, by contrast, hits 77 percent and returns almost nothing after costs, because the possible gain is smaller than the risk.

The comparable figure is the average result per trade after costs – everything else can be dressed up through the exit rule. The full ranking of every pattern we measured is on the chart pattern backtest page.

Red flags worth walking away from

• Return promises in percent per month.
• No indication of how many signals arrive per week – you cannot tell whether you could even keep up.
• Only winners in the channel; losers disappear without comment.
• Signals without a stop loss. Without a defined loss it is not a signal, it is an opinion.
• Pressure to decide immediately ("today only", "last seats").

How we do it

We publish every signal with entry, stop loss and target line before the outcome is known – and then settle all of them under the same rules with 0.1 R of costs. The result is uncomfortable and public anyway: our Wolfe Wave signals come to −0.06 R per trade live, while the backtest of the same rules shows +0.37 R. That gap between test and reality is exactly what most providers leave out – see the Wolfe Wave backtest.

How WolfeWaveSignals does it

We show our full performance with winners and losers, every signal comes with entry, stop-loss and target line, the method is a transparent scanner, the subscription is cancellable monthly, and four current signals are always free to view.
