Strategi ini menggunakan titik-titik pivot (PivotHigh dan PivotLow) untuk mengenal pasti swing high dan low dalam harga dan menarik trendline ke atas dan ke bawah berdasarkan titik-titik ini. kemiringan trendline dikira menggunakan kaedah seperti ATR (Rentang Benar Purata), penyimpangan standard, atau regresi linear, dan kemudian disesuaikan dengan faktor kemiringan. Apabila harga memecahkan trendline, strategi menghasilkan isyarat beli atau jual.
Strategi ini menggunakan titik pivot dan cerun trendline untuk membina sistem perdagangan trendline masa nyata. Dengan menangkap peristiwa pecah trendline, strategi ini dapat berdagang pada peringkat awal pembentukan trend. Walaupun strategi ini mempunyai kelebihan tertentu, masih perlu untuk menyedari risikonya di pasaran yang bergolak dan meningkatkan lagi kekuatan dan keuntungan strategi dengan memperkenalkan lebih banyak maklumat, mengoptimumkan penapisan isyarat, pengurusan kedudukan, dan kaedah lain.
