Asking for advice

Forex is a highly liquid type of earnings. I never wait for benefit long. I open one
order with the whole volume of deposit as long as margin allows. As a result you get all
or nothing. It’s brilliant for such strategy if broker gives bonuses. But I heard that many
brokers do a great deal of sharp manipulations with these bonuses. I’d like to find
an incorrupt broker. Please somebody tell me where to find such information.
