यह रणनीति एक रणनीति है जो बहुत पहले क्रिप्टोक्यूरेंसी 796 फ्यूचर्स एक्सचेंज पर लागू थी। वायदा अनुबंध क्रिप्टो-मार्जिन है, अर्थात, मार्जिन मुद्रा से घटाया जाता है (उदाहरण के लिए, बीटीसी अनुबंधों में, यह बीटीसी से घटाया जाता है), और अनुबंध आदेश राशि दशमलव हो सकती है, जो कि बिनेंस क्रिप्टो-मार्जिन अनुबंध के समान है। रणनीति को रणनीति डिजाइन अध्ययन के लिए लिया जाता है, तर्क प्रसंस्करण अभी भी बहुत अच्छा है, इसलिए रणनीति मुख्य रूप से सीखने के लिए है।

रणनीति कोड पढ़ने के बाद, आप पा सकते हैं कि रणनीति तर्क जटिल नहीं है, और कोड बहुत ज्यादा नहीं है, लेकिन डिजाइन सरल है और इसके कई हिस्सों का उपयोग संदर्भ के लिए किया जा सकता है।
रणनीति व्यापार तर्क का मुख्य कार्य हैloopसमारोह है, जो बार-बार मुख्य लूप में बुलाया जाता हैmainकार्य।loopफ़ंक्शन शुरू होता है, पहले पदों को पकड़ने के लिए ऑर्डर रखें, और फिर लाभ लेने के आदेशों को पेंड करें और स्टॉप-प्रॉफिट ऑर्डर के निष्पादन की प्रतीक्षा करें। फिर, निम्नलिखित दो सामग्री का पता लगाने के लिए पता लगाने की स्थिति दर्ज करें।
रणनीतिक तर्क का वर्णन सरलता से किया गया है, लेकिन अभी भी कुछ अन्य विवरण हैं, जैसे कि अधिकतम रिवर्स की संख्या निर्धारित करना, उपलब्ध खाता परिसंपत्तियों का पता लगाना और अधिकतम विफलताओं की संख्या को 10 गुना तक संसाधित करना।
रणनीति में कुछ कार्यों को विभिन्न मापदंडों के अनुसार अलग-अलग प्रदर्शन करने के लिए डिज़ाइन किया गया है, जैसेःStripOrdersकार्य,GetAccountकार्य,GetPositionइन कार्यों में आयातित मापदंडों के अंतर के आधार पर अलग-अलग क्रियाएं होती हैं। यह कोड का अच्छा उपयोग करता है, और कोड अतिरेक से बचता है, और रणनीति डिजाइन को संक्षिप्त और समझने में आसान बनाता है।
