Strategi arbitraj intertemporal yang telah ditulis sebelum ini memerlukan input manual spread lindung nilai untuk membuka dan menutup kedudukan. menilai perbezaan harga adalah lebih subjektif. Dalam artikel ini, kita akan menukar strategi lindung nilai sebelumnya kepada strategi menggunakan penunjuk BOLL untuk membuka dan menutup kedudukan.

Tetapan parameter strategi:
Rangka strategi keseluruhan pada dasarnya sama denganVersi Python strategi lindung nilai intertemporal niaga hadapan komoditi, kecuali bahawa parameter penunjuk BOLL yang sepadan ditambahkan. Apabila strategi berjalan, data K-line kedua-dua kontrak diperoleh, dan kemudian perbezaan harga dikira untuk mengira spread.TA.BOLL
fungsi untuk mengira Bollinger Bands. Apabila penyebaran melebihi rel atas Bollinger Band
