From the perspective of tangent theory, the cashbackforexbtc East forex cashback forexcashbackcalculator a part of it, it is the fluctuation of the price of the low Eastforexcashback low cashback forex of the connection or high point and high point of the connection and the formation of a straight line forex financial investment training to remind traders, if the price is running according to a low point than a low point to run the way, the trend line drawn is an uptrend line; if the price is a high point than a high point to run the way, the trend line drawn is a downtrend line; if the price is By a high point than a high point of the way to run, the trend line drawn is a downward trend line There is also a price of the low and high point of the horizontal extension, no obvious up and down trend, which is the horizontal finishing or called box finishing Trend line can be divided into support and pressure lines, the price band running low and low point connected into a straight line, is the support line; the price band running The length of the trend line is directly proportional to its importance. The distance between the first and second points of the long-term trend line and the medium-term trend line should not be too close, such as too close, the importance of the trend line formed will be reduced Support and pressure lines can be transformed into each other, when the foreign exchange price breaks through a support line from above, the original support line will probably be transformed into a pressure line; and When the price breaks through a pressure line from the bottom up, the original pressure line will probably also be transformed into a support line forex pass financial investment training pointed out that some times, we can find that the exchange rate runs between two parallel trend lines, the line above the pressure line, the line below the support line two trend lines constitute a channel or pattern The angle of the trend line is critical, too gentle angle shows that the strength is not enough The trend line is not easy to produce a big market; too steep trend line is not sustainable, often prone to quickly change the trend of the famous angle line master Gann believes that: 45 degrees of the angle of the trend line is very reliable, that is, Gann said the 11 angle line In drawing the trend line points tips: 1, the trend line according to the length of price fluctuations are divided into long-term trend line, medium-term trend line and short-term trend line, the longer the time period, the more effective the trend line. The longer the time period, the higher the effectiveness of the trend line; 2, forex financial investment training pointed out that the number of highs or lows connected to the trend line, the stronger the effectiveness; 3, the trend line should not be too steep, 45-degree angle reliability is higher otherwise it is easy to be broken by the horizontal finishing, the loss of analytical significance
