I’m sorry to hear it.
If someone had enough forex trading knowledge and experience to be able to produce reliable, steadily profitable signals, one would perhaps wonder why would they want to sell them, rather than just trading their own account with them? If there is a signal service that just “works”, It’s not going to be one that you can buy through an advertisement in a forum. Those can’t work reliably and be profitable, because they wouldn’t be for sale in that way, if they were. Many are marketed by people without the necessary skill-set even to [I]determine[/I] whether or not they’re genuinely profitable, and even more are sold by by people who have deliberately backfitted them to appear to be profitable, knowing that in this “desperate buyers’ market” there are many naive and gullible potential customers who won’t appreciate the reasons for the absolute lack of correlation between something having made a profit over the [U]previous[/U] year (for example) and its probability of making a profit over the [U]next[/U] year. (That’s “profitable systems/signals”, though - not necessarily 100% of “profitable education”, which is something altogether different.)
In the late 1990’s, a group of American academics (mathematicians, physicists, engineers, computer scientists, economists and others) got together and developed a profitable trading system more or less reduceable - in expert hands - to signal-producing software, which they then successfully leased to [I]Credit Suisse[/I] for a large six-figure monthly sum and a percentage of its profits. Major trading institutions pay people large salaries to assess such “profitable systems” and have close-to-infinite funding available for their acquisition and development. One doesn’t have to be Einstein to appreciate that genuinely “profitable systems/signals” are marketed that way, [B]not[/B] by being advertised online to retail traders!
A lot of figures like this are bandied about, usually without sources being quoted for them.
What [I]are[/I] sometimes published are verified, independently audited accounts collated from the records of brokers, showing what proportions of their clients make profits. It’s true that these generally make depressing reading. To me, the striking feature about them is always the disparity in proportions of winners and losers between [I]genuine brokers[/I] and [I]counterparty market-makers[/I] who trade against their own clients and therefore have an incentive for their clients to lose money.
In case you’re unfamiliar with these terms, a genuine broker is someone who executes trades on your behalf in the underlying market (in the case of forex, that’s the interbank market): they’re simply providing a service in exchange for a commission. They’re not themselves directly involved in the transaction and have no incentive for their clients to lose. A counterparty market-maker is someone pretending to be a broker who actually holds the other side of his own customers’ trades, while also holding their deposited funds and both making up and interpreting all the rules governing every trade.
It’s certainly not easy.
It might be true that he does it. It’s not true that he makes steady profits from it, and that’s easily verifiable by getting hold of some automated, backtesting software (widely available at low cost) and checking how it does over 5,000 trades (no need to, though: I can tell you that it loses money over the long term, as every trivial moving average crossover system does and must - and of course there are reasons for that. They’re good and valid and reliable reasons, and in the long run they apply to your friend just like they do to everyone else).
My own suggestion for you is not to trade with real money until you [B]know[/B] that the system you’re trading has an edge (positive net expectation).
To learn whether or not it does will take quite a bit of education and practice, of course. But that’s what textbooks and demo accounts are for.
I offer one tip: be [B][U]very[/U][/B] wary of “information” offered by people who are selling/promoting anything, in this industry.
Welcome to the forum, and good luck!
