What a signal contains
A signal is four things: instrument, direction (up or down), timeframe and horizon. Plus a score — how strongly the factors you enabled agree with each other.
What it does not contain: entry price, target, stop and profit. That is by design, not an omission. Your entry depends on when exactly you press the button at your broker; the result depends on your volume, leverage and fees. The service has no access to your account and cannot name those numbers.
Why the decision is made on closed candles
Indicators are computed on closed candles. An unclosed candle is still changing: what looks like a breakout a minute before the close often turns out to be a wick by the time it closes. Computing on an unclosed candle is looking into the future, and in a historical run it produces pretty numbers that never appear in real life.
The consequence: the signal arrives after the deciding bar closes, not in the middle of it.
What the horizon means
The horizon is the period over which the signal's claim is checked. An hour means that an hour later the service looks at where the price went and records the outcome. Statistics are built from these outcomes: the share of confirmed signals, price movement, drawdown.
The signal's outcome is not the result of your trade. You may have entered later, exited earlier, placed a closer stop — and got something else. The trade journal shows the difference.
Score and threshold
Every enabled factor votes with its own weight. The sum of votes is the score. If it does not reach the threshold, no signal is issued at all. See the article on the threshold and the minimum number of cores.
