Auto Channel Detector And Plotter

Channel trading is one of the most popular trading method now a days. But it is also very important to draw a correct trend line or channel. Highly Accurate Auto trendline Channel Plotter afl can helps you in this regard. This afl automatically detects the trendline points and connects them to form a accurate trendline or channel. An entry can be made after breaking channel support/resistance or at the pull back. This afl is ideal for intraday as well swing traders but it works great in case of swing trading with daily time frame.
