Strategi ini menggabungkan peta haba jumlah dan harga masa nyata untuk menjana isyarat beli dan jual dengan menganalisis pengedaran harga dan jumlah dalam tempoh tertentu. Strategi pertama mengira beberapa tahap harga berdasarkan harga semasa dan peratusan julat harga yang ditetapkan. Ia kemudian mengira jumlah beli dan jual pada setiap tahap harga dalam tempoh yang lalu dan mengira jumlah beli dan jual kumulatif. Warna label ditentukan berdasarkan jumlah beli dan jual kumulatif. Di samping itu, strategi merangka kurva harga masa nyata. Di samping itu, strategi menggabungkan penunjuk seperti EMA dan VWAP untuk menjana isyarat beli dan jual berdasarkan hubungan mereka dengan harga dan jumlah. Isyarat beli dihasilkan apabila syarat beli dipenuhi, dan tiada isyarat terdahulu berlaku. Isyarat jual dihasilkan apabila syarat jual dipenuhi, atau terdapat dua lilin merah berturut-turut, dan tiada isyarat terdahulu berlaku.
Strategi ini menjana isyarat beli dan jual dengan menggabungkan peta haba jumlah, harga masa nyata, dan beberapa penunjuk teknikal, menyediakan nilai rujukan tertentu. Keuntungan strategi ini terletak pada kemampuannya untuk menampilkan pembahagian harga dan jumlah secara intuitif dan secara menyeluruh mempertimbangkan beberapa faktor untuk menjana isyarat. Walau bagaimanapun, strategi ini juga mempunyai beberapa batasan dan risiko, seperti kesan tetapan parameter, sifat ketinggalan indikator, dan bergantung pada pasaran trend. Oleh itu, dalam aplikasi praktikal, pengoptimuman dan peningkatan strategi yang lebih lanjut diperlukan, seperti memperkenalkan lebih banyak penunjuk, mengoptimumkan keadaan isyarat, meningkatkan kawalan risiko, dan lain-lain, untuk meningkatkan kekuatan dan keuntungan strategi.
