One of the biggest mistakes by many trader is to rely on a lagging or repainting indicator to determine price direction from the content in the video it look like a smooth ride to making profits due to the fact the price was trending bullishly while the CME premium seem to comply with the trend and adjusted to a minor retracement of the price, which will definitely work in any price trending condition, however when the price begin to range that is when the indicator tend to fail, of course live trading will reveal alots about the inaccuracy or inadequacy of the indicator, however I think traders should rely more with their brain i.e mental decision with lesser reliance on indicators when taking a trading decision.
