Since most indicators are based on the underlying price, one could say that there is nothing new under the sun.
One could also say the same about any tools of any kind. A hammer and saw is probably all a builder needs to build a basic house, yet there are tools that offer better productivity - if used by someone with the right skills for them.
More important than the question of whether these indicators are an improvement or not, is the question of whether a better use is found for them.
It is not the usefulness of indicators themselves that will make a trading career out of a bunch of formulae, but the trader's application of these tools to his/her trading strategies.
Don't ask what indicators can do for you - ask what you can do with indicators.
