It is usually difficult to find reliable signal providers to continue with them in long term. Same is true to become a long term signal provider as well.
Because for someone to become a popular signal provider, he has to make very high % consistent daily return, otherwise, no one will even look into the signals. In order to do that obviously the signal provider has to take high risk in his account.
Next, once it becomes a little popular and number of subscribers become more, it becomes the target of big players like brokers or funds who can just manipulate the market price a couple of times so that the account will be wiped out and signal will collapse.
Many of the subscribers who have been following signals here will agree with me for most of the signals. Only those signals which makes a very low % return may continue for long time, but again the signal provider may not find much subscribers and he might be profitable even more by offering MAM.
In my perspective, the best practice is to start taking control of the signals and it's followers amounts etc once it becomes popular to fully monitor the trades and it's activity so that the trades or trading system will not be misused or manipulated by big players.
Though I was not sure whether to provide signals or offer MAM service, finally I have decided to start as a signal provider first in high risk mode and then, proceed from there. My signals might be available within next few days or weeks.
I have already ventured on this path that you have described above -- over the past 25 months. And I have done all the things you are talking about.
I do not wholly agreed though about brokers/funds targeting a signal once it becomes popular. No intervention or manipulation on their part can have anything to do with open trades of a signal provider. these are straw man arguments. common excuses for poor performance.
Have a look at my systems and you will find what consistency and resilience are all about on this 'risky journey'.
I have to agree that so far you have maintained a overall good trading profile.
However, I am referring here about high risk traders who target high monthly % return like 100%,200% per month and not about low risk traders targeting 5% to 20% per month.
Obviously, it is very difficult to affect the trades of a low risk trader by any large entity or corporation as well, because in order to do that the market has to move hundreds of pips in one side which is usually impossible except for technical glitch or flash crash events etc.
But for a high risk trader where his margin call or max DD is 20 to 40 pips away and who is trading millions of USD using high leverage can be easily affected by a big player and a regular broker or hedge fund can easily do that for sure.
