Hence a chart is background, it's exactly what HAS happened. They are useful to some trader but one shouldn't be trying to acquire an advantage from a chart. If you think about the amount of retail traders who neglect, what do they seem to do that is actually common? You must get the job done away from the chart and use the chart for risk. When a chart is rising/falling, how can you know it will'last' to rise/fall? .... The only way you'll know not or whether it will last is to track the price driver and not the chart. If the price driver stays, then the motion in price continues in that direction.
