Strategi SR Breakout adalah strategi penembusan rintangan sokongan yang dibangunkan berdasarkan indikator penemu penembusan LonesomeTheBlue. Gagasan utama strategi ini adalah untuk menghasilkan isyarat melakukan atau melakukan dengan menilai sama ada harga tutup telah memecahkan tahap sokongan atau rintangan.
Strategi SR Breakout adalah strategi perdagangan berdasarkan idea pemecahan rintangan sokongan klasik, dengan menggunakan fungsi pivothigh dan pivotlow untuk mengira tahap sokongan dan rintangan, dan menghasilkan isyarat perdagangan dengan menilai sama ada harga penutupan menembusi kedudukan tersebut. Kelebihan strategi ini adalah pemikiran yang jelas, mudah dilaksanakan dan dioptimumkan; tetapi terdapat juga beberapa risiko, seperti prestasi yang buruk dalam keadaan yang bergolak, dan risiko yang mungkin dibawa oleh kadar stop loss yang tetap.
