The "perfect technical indicator" is a trap. Unfortunately, many users of technical analysis software have fallen into the perfect indicator trap. Convinced of their programs power, these users undertake a determined search to find the perfect indicator(s) that will lead them to trading success.
It is, for them, a silver bullet that will slay the market. Somehow, the indicator is supposed to correctly predict a security's price movement on every occasion. Its perfect entry is supposed to produce financial results that many people only dream of. However, most successful traders have come to realise that no such perfect indicator exists. It doesn't today, never did, and never will.
There is no Holy Grail of trading. There is no set of conditions that will let you know without fail how to make a profitable trade every time. Do not get sidetracked by the idea that a Holy Grail may exist. The reality is that any charting software for that matter, is simply a tool to be used in your decision making process!
