Are Forex Signals Worth It? The Expectancy Math That Decides

Forex signals are worth following when the expectancy is positive after costs, and worthless otherwise. That sounds obvious and almost nobody checks it, because the number everyone quotes, the win rate, does not answer the question on its own. A 70 percent win rate loses money at the wrong reward-to-risk, and a 40 percent win rate makes money at the right one.

This page shows the arithmetic, the break-even win rate for each reward level, what execution costs remove from it, and the specific things that make a feed unfollowable even when the calls are good.

• Win rate alone tells you nothing. Win rate plus reward-to-risk tells you everything.
• At 1.5R reward you need 40 percent. At 1R you need 50. At 0.5R you need 67.
• Costs come out of every trade, and on tight stops they are a large share of the edge.
• Missed calls are part of your result even though they are not part of theirs.
• Thirty trades is the minimum before the numbers mean anything.

The arithmetic

Expectancy is what one trade is worth on average, expressed in R, where 1R is the amount you risk per trade.

expectancy = (win rate × average win in R) - (loss rate × average loss in R)

55% win rate, wins average 1.5R, losses average 1R:
(0.55 × 1.5) - (0.45 × 1) = 0.825 - 0.45 = +0.375R per trade

Positive, so the feed is worth following in principle. Now do the same for a feed with a far more impressive-sounding win rate but a tight target:

75% win rate, wins average 0.5R, losses average 1R:
(0.75 × 0.5) - (0.25 × 1) = 0.375 - 0.25 = +0.125R per trade

Still positive, and a third as good as the 55 percent feed. This is why the win rate on its own is a marketing number rather than an analytical one, and why it is the one number every signal seller leads with.

The break-even win rate for each reward level

Set expectancy to zero and solve. This is the win rate a feed must beat just to break even before costs.

So when a channel advertises "85 percent win rate" and every call targets 10 pips with a 40 pip stop, that is 0.25R reward, requiring an 80 percent win rate to break even. The advertised number is above break-even by five points, before costs, which will take more than that.

What costs remove

Every trade pays the spread and commission whether it wins or loses, and it comes out of the R.

cost in R = cost per round turn / stop distance

2.5 pips all-in cost, 30 pip stop:  2.5 / 30 = 0.083R per trade
2.5 pips all-in cost, 10 pip stop:  2.5 / 10 = 0.25R per trade

On the 30 pip stop, an expectancy of +0.375R becomes +0.292R. Survivable. On a 10 pip scalping stop, the same cost eats a quarter of your risk unit on every single trade, and a feed with +0.125R expectancy is now firmly negative.

This is the single most common reason a feed that looks good on paper loses money live: the published results are calculated on mid prices, and you trade at the spread. The tighter the stops, the worse the gap.

The costs that are yours, not theirs

A provider's published record is the best case. Yours will be lower, for reasons that have nothing to do with signal quality.

• Missed calls. If a third of the calls arrive while you are asleep, your result is the two thirds you actually took, and there is no reason those will be the same mix of winners as theirs.
• Delay. You see the call, read it, size it, place it. On a swing setup that costs nothing. On a scalp it is a meaningful part of the entry.
• Slippage. Their fill is not your fill, and both get worse around news.
• Discretion. Skipping the calls you dislike sounds prudent and it changes the distribution. You are no longer following that feed, you are following a filtered version whose statistics nobody has measured.

How many trades before the numbers mean anything

Thirty is the practical minimum, and a hundred is where you start to trust it. Below thirty you are mostly measuring luck. A feed with genuine positive expectancy will still show losing runs of five or six inside any normal month, and a feed with no edge will produce a stretch of ten winners often enough to sell subscriptions off it.

Judge the worst streak in the sample, not the best. It sets your position size, because surviving it is the whole game.

So are they worth it

Worth following if: the calls carry an entry, a stop, targets and risk as a percentage; they are posted before the outcome is known; the losing calls remain visible; the reward-to-risk is above 1 so the break-even win rate is under 50 percent; and the holding times are long enough that spread is not most of the edge.

Not worth following if: the win rate is the headline and the reward-to-risk is not published; results are screenshots rather than a live feed; the calls are given in fixed lots; or the stops are so tight that costs consume a quarter of the risk on every trade.

And they are never a substitute for position sizing. A feed with positive expectancy still loses your account if you size it wrong, which is the part nobody else can do for you.

What we do

Our forex and gold calls go out on Telegram the moment we take the trade, with the entry, the stop, the take profit levels and the risk as a percentage. They are posted before the outcome is known and the losing ones stay up, which is what makes the record scoreable rather than decorative.

There is no subscription. A partner broker covers it through a rebate on spread you were paying anyway, so there is no monthly fee and no profit share. You place every trade yourself.
