Status: Per-family deep reference (companion to the consolidated Fusion AI Studio & ONNX User Guide) Audience: first-time AI Studio user Answer family: Up / Down Prediction style: Classification
Up / Down asks:
“Will the close N bars ahead finish above the current close?”
This is the simplest directional classification family in AI Studio.
It gives the model only two choices:
1 = up0 = not upThat makes it easy to start with, but also easy to misunderstand.
Example:
Target_UpDown10Meaning:
Target_UpDown10[t] = 1 if Close[t+10] > Close[t] else 0
Plain-English translation:
10This is not the same thing as:
1 = long
0 = short
That is the main trap with this family.
Up / Down is a binary direction question, not a full long/flat/short system.
It only asks:
“Did price finish higher by the end of the horizon?”
It does not tell you separately whether the bar finished:
Those all collapse into the same label:
0 = not up1 and 0 MeanThis family is easiest to understand if you think of it this way:
1 = future close finished above current close
0 = future close did not finish above current close
That means class 0 mixes together:
If you want:
+1 = long0 = flat-1 = shortthen Direction (3-Class) is usually the better answer family.
This family uses the normal Step 1:
Fixed-Horizon Windows (bars)If Step 1 says:
1,5,10,20
Fusion can create:
Target_UpDown1Target_UpDown5Target_UpDown10Target_UpDown20Then Step 2 chooses one of those columns for one model.
For Up / Down:
Look-ahead Windows mattersThis is a classification family.
The correct trader meaning is:
1 = up
0 = not up
The saved model contract may still need class decoding to turn the encoded class id back into the human meaning.
So the right mental model is:
decode the class, then interpret it
not:
treat the raw plotted encoded number like a smooth oscillator
Even though it is not a clean long/short target, it can still be useful when the user wants:
Direction (3-Class)This can be a good beginner family because it is easy to explain:
“Will the future close be above the current close?”
This is where users often make a mistake.
They see:
1 = long
0 = short
But that is not what the label means.
It really means:
1 = up
0 = flat or down
So if a user wants a direct short signal family, Up / Down is usually too blunt.
That is why Direction (3-Class) is often the cleaner trader-facing classification family.
Up / DownAsks:
“Did price finish up or not up?”
Output:
1 = up0 = not upDirection (3-Class)Asks:
“Did price finish down, flat, or up?”
Output:
+1 = up0 = flat-1 = downSo the simpler family is:
Up / DownBut the clearer trading family is often:

0 as a clean short labelHere, 0 means not up, not strictly short.
It does not. Flat and down are mixed together in the 0 class.
That belongs to Direction (3-Class), not Up / Down.
Decode the class meaning first.
These are the product improvements this guide exposes.
0 means not upSuggested note:
“Up / Down is a binary target. Class 1 means the future close finished higher. Class 0 means not up, which mixes flat and down bars.”
Suggested compact display:
Up / Down
binary class | 1 = up | 0 = not up
Suggested note:
“If you want explicit short / flat / long behavior, Direction (3-Class) is usually clearer.”
Up / Down means:
“Predict whether the close N bars ahead finishes above the current close, where class 1 means up and class 0 means not up.”
