I think 5 timeframes is an overkill but if it is working out for you then well and good.
Handling 5 timeframes together is never overkilled for me and as a matter of fact, it's as flawless to the point that I conclude all the analysis in less than 1 minute. That must surprise you, but you shouldn't be surprised, my only time-consuming strategy which is Trendline has been automated, so it's easy for all my strategies to be read on each timeframe in less than 10 seconds.
That is indeed surprising to me because it's hard to believe that you can read strategies in less than 10 seconds.
But if it's working out well for you then I am happy for you. On the automation part I am impressed because I am finding ways to automate strategies myself.
Firstly, I am looking for indicators which can give me the right analysis and may be then I will try to automate it.
What I am confused with is that one strategy doesn't work for all coins/stocks and different timeframes.
I did find one strategy but it just worked on one stock and few coins and also just on one timeframe.
When I changed the timeframe the results were not so good.
You should not be surprised my friend, these are strategies that are always instantly loaded upon opening the trading platform, so reading them are fast, just like glancing at a thing and immediately you know what they are and what they can do. Also, I believe you need more practice to actualize your goal of a good trading system.
But be sure to know that the trading system might not be the issue at times, many abandoned a good strategy because of that not knowing that no strategy is perfect and traders can't be successful without proper money and risk management to complement the strategy. And good strategy could be one or more, it doesn't matter.
