Seriously, retail traders trading with direct market access that the banks could manipulate to "take out stops" consist of a fraction of one percent of the overall forex market. A market that is primarily made up of banks executing business strategies on behalf of their clients. Additionally, banks are now prohibited from operating trading divisions and have shut those operations down and laid off thousands who used to staff them. Even if the remaining operations are trading under the guise of hedging, they don't have the financing to just arbitrarily move markets up and down, and they've zero motivation to take the risk of doing so with the double layer of scrutiny they are under. Especially not to take $10k off a punter by blowing their stop. You're flattering yourself into being far more important than you are if you put any credence into this kind of conspiracy theory, all the more so since it's backed by no evidence except your failure to make money in the market which must be the fault of someone else.
