| # Candlestick pattern detection dataset |
|
|
| 640x640 renderings of 20-candle daily OHLC windows, with YOLO-format boxes for |
| 8 candlestick patterns. |
|
|
| ## Labels are rule-based, not human-verified |
|
|
| Every box was generated by TA-Lib's `CDLxxx` functions. Nobody annotated these |
| charts by hand. A model trained here learns to imitate TA-Lib's published |
| heuristic, which does not always agree with what a discretionary trader would |
| mark on the same chart. Treat the labels as a reproducible rule, not as truth. |
|
|
| ## Splits are chronological, with an embargo |
|
|
| | split | period | |
| |---|---| |
| | train | through 2014-12-31 | |
| | val | 2014-12-31 to 2018-12-31 | |
| | test | after 2018-12-31 | |
|
|
| Consecutive windows overlap in 19 of 20 candles, so the first |
| 20 windows after each boundary are discarded. Val and test |
| images therefore share no candle with any training image. Splits are never |
| random. |

|
| `train` also contains auxiliary large-cap tickers |
| (AAPL, MSFT, JPM, XOM, JNJ, KO, GE, WMT, PG, T), included solely to give the rare |
| three-candle patterns enough examples. `val` and `test` are |
| SPY-only, so held-out metrics describe the instrument the downstream |
| study actually uses. |
|
|
| ## Layout |
|
|
| ``` |
| images/{train,val,test}/TICKER_YYYYMMDD.png |
| labels/{train,val,test}/TICKER_YYYYMMDD.txt |
| ``` |
|
|
| A filename's date is the window's **last** candle: the chart contains bars up to |
| and including that date and nothing after it. |
