|
|
Double-barrier labeling:
|
|||
|
|
- For each index i, define:
|
|||
|
|
upper_barrier = close_i * (1 + up)
|
|||
|
|
lower_barrier = close_i * (1 - down)
|
|||
|
|
- Look ahead up to 'horizon' bars to see which barrier is touched first.
|
|||
|
|
- Label = +1 if upper barrier touched first,
|
|||
|
|
-1 if lower barrier touched first,
|
|||
|
|
0 if neither is touched within horizon.
|
|||
|
|
df must have a 'close' column.
|
|||
|
|
Returns a new DataFrame with a 'barrier_label' in {-1, 0, +1}.
