i must confess, even at this early stage of my learning, i am sceptical of signal generators. though i cannot define why, my feeling towards them is always negative, maybe its something to do with me not being happy with things that i am neither in control of nor understand!
You do not like signal generators because they are not your signals. You might be happier using your own entry and exit points based o your own observations. Whatever you do, any entry point will probably be based on historical data. It's cheaper to use your own. However, once in the trade, it is a different ball game. Something like riding one of those bulls at a fairground. I try to use a target but, I admit, quite often decide to take profits. At least, I'm still trading! Whatever you do, Good Luck with it.
