Giving below the THEORY that says, the difference between TUESDAYS high minus Low, should be the target to the downside, breaking below Tuesdays Low. For EXAMPLE- High is 39800. Low is 39000. Hence 39800 minus 39000 = 800 points. So the Downside Target Must be 39000 minus 800 = 37200. Always Remember the story does not END here. The market MAY decide that it wants to go lower than 100% retrace, hence we call these EXTENSIONS . So the market may extend to the downside by 100, 112.6, 123.6, 150,178.6, 200, 212.6 % etc etc etc . Learning these Basic rules will help you all go a Long way in making your Trades. Random Buying / Selling without any understanding is Not the way
