یہ حکمت عملی شارٹ ٹریڈنگ کے لئے مشہور ٹرتل سسٹم کو اپناتی ہے ، جس میں نیچے کے رجحانات میں اہم سپورٹ وقفوں پر پرامڈائزنگ ہوتی ہے۔ یہ ایک عام رجحان کے بعد بریک آؤٹ پرامڈائزنگ سسٹم ہے۔
حکمت عملی منطق:
10 دن، 20 دن اور 55 دن کی کم ترین سطحوں کو اہم سپورٹ کی سطح کے طور پر مقرر کریں۔
20 دن یا 55 دن کی سپورٹس کے وقفے پر مختصر داخل کریں.
تجارت کے دوران ATR کے مقررہ ضرب کی ہر خلاف ورزی پر مختصر پوزیشن میں شامل کریں۔
جب قیمت 10 یا 20 دن کی بلند ترین سطح سے نیچے آجائے تو منافع حاصل کریں۔
اے ٹی آر سٹاپ نقصان کا استعمال کریں، ٹرگر ہونے پر باہر نکلیں.
پیرامیڈائزنگ اور سٹاپ نقصان کے لیے اپنی مرضی کے مطابق اے ٹی آر ضرب۔
فوائد:
حمایت کے وقفے کمزور الٹ کی نشاندہی کرتے ہیں.
پیرامائڈنگ بڑے فوائد کے لئے رجحانات میں سائز جمع کرتا ہے.
اے ٹی آر سٹاپ بدلتی اتار چڑھاؤ کے مطابق ڈھال لیتا ہے.
خطرات:
حمایت کی شناخت میں تاخیر مثالی اندراجات کو یاد کر سکتی ہے.
پرامڈائزنگ تیزی سے خطرات کو بڑھا دیتی ہے، جس سے محتاط پوزیشن سائزنگ کی ضرورت ہوتی ہے۔
سمت کے نقصان کے سائز پر کوئی حد نہیں، ممکنہ طور پر بڑے کھپت.
خلاصہ میں ، یہ حکمت عملی اے ٹی آر ٹریلنگ اسٹاپس کا استعمال کرتے ہوئے اہراموں کو مختصر کرتی ہے۔ بہتر پیرامیٹرز کے ساتھ ، یہ مضبوط حرکتوں کو بتدریج پکڑ سکتا ہے لیکن اس کے لئے مرکوز خطرات کا انتظام کرنا ضروری ہے۔

// This is the short sell version of the strategy based on the famous turtle system.
// https://www.tradingblox.com/originalturtles/originalturtlerules.htm
//
// In a nutshell, it a trend trading system where you are shorting on strength (in the downtrend), selling on
// weakness (that it might be reversing).
// positions should be entered when the price crosses under the 20-day low (S1 low) or 55-day low (S2 low).
// positions should be exited when the prices crosses over the 10-day high (S1 high) or 20-day high (S2 high)
// you can add positions at every unit (measured by multiple of n, where n=1 ATR)
// stops should be placed at 2*n above every position entered, when the stop is hit exit your entire position.
// positions should be entered everytime price crosses under S1 or S2, with one exception:
// if the last trade was an S1 trade and it was a winning trade, skip the next trade unless the price crosses
// under S2, if that is the case, you should take it.
// S1 and S2 levels are also configurable for high and lows.
// N multiple for stops and pyramid are also configurable
// To change this from a strateg to a study:
// 1) uncomment the next line and comment out the strategy line.
// 2) at the end of the file comment out the last 2 lines
