To add my 2c worth there's a factor that I think is used to exploit inexperienced traders lure them into paying for what *appears* to be the most lucrative signal_service frequently resulting in the demise of their account.
that is
the measure of success of these signal_services. Should it be:
- Pips moved per entry exit? totalled over a period of time?
- Monetary gain on an account over a period of time?
- Percentage gain on account capital over a period of time?
Well to all the newbies experienced traders - there is only one true measure of trading success. that is the first option - pips gained/lost. (For those who aren't sure - a pip is the smallest measure of a currency p's move - eg. 0.0001 Euros on EUR/USD p or 0.01 Yen for the USD/JPY p)
Claims of monetary gain % gain are false measures since they do not factor in the leverage account size position size that will definitely vary one trader to the next.
Measuring the number of pips moved (in your favour or against you) is a measure that is independant of the trader's account size the leverage they use the position size that they take. therefore it is a measure that is independant of the RISK that a trader takes. Adding up the losses gains each month/quarter then charting the nett result per month/quarter would indicate the sustainability of the signal_service's success. (You could even plot a moving average through this chart to smooth out the peaks troughs).
I advise people to keep away services sites that claim ludicrous monetary or percentage gains. To coin a phrase: "If it sounds too good to be true it probably is."
So what is a reasonable nett pip gain to be expected a respectable signal_service per month? In my opinion any signal_service that is sustainably returning 500 pips per month (or more) is *exceptionally* good. These are far few between. Factor that in to your account size position size per trade leverage you can calculate your own monetary percentage returns. They will probably be higher than what I expect. But then I have been around the block a few times. I hope my opinion is helpful.
