Two key things involved with market Analysis is all about Identifying the Demand and Supply zones, which we call support and resistance (accumulation & distribution). Note: only M, W, D1 time frame can stand as a strong support and resistance, i.e using this time frames in identifying the lowest level and highest level in the market.
I have mentioned this many times on this forum, that newbie traders should always know that indicators can be helpful, but they can also fail, but more accurate with larger time range. Depending fully on indicators can fail traders, they need strategies, other type of analysis and risk management to be able to make money from trading.
The only thing i can implies on this, is that many people have different tool or different method of surviving in trading but they will not like to disclose their own methodology. So i believe that when you devote out time in something they is every tendency that you will know the possible escape root to follow.
What kind of tools and indicators will they not want to disclose? Trading is risky and they want to use it to make money is not easy to learn, but a consistent trader will learn more as he continue to trade. There is nothing hard in trading if you look for better strategies that can help while common indicators are enough along side with it.
It seems that until now I have never done an analysis using tools or similar services which are widely available, because I myself don't really trust it.
You do not trust what you do not learn and know about, that is wrong. You have your own way of analysing the market? But no way to be 100 percent accurate, no matter how good the analysis, there are sometimes it may fail, trading is more than just using indicators.
