ifstoch ve macd indikatörlerinin birleşimi

Merhabalar aşağıdaki pine script kodnda ifstoch ve macd indikatörlerini birleştirerek aşırı alım ve satım noktalarında macd indikatörünün aşağı ve yukarı kesimlerinide katarak al ve sat kodu oluşturdum.
Al ve sat üzerine alarm kurabilirsiniz.
if stoch yukarı çıkarken macd indikatöründen gelen al sinyalı yapmak veya tersi tavsiye ederim
