this has nothing to do with brokers being 'scam' or legit. Almost all brokers protect themselves against arbitrage (i.e. exploitations of delays in their price feed) through their terms and conditions. Heres an excerpt of AvaFX's T&Cs:
'Internet, connectivity delays, and price feed errors sometimes create a situation where the prices displayed do not accurately reflect market rates. The concept of arbitrage and 'scalping', or taking advantage of these Internet delays, cannot exist in an OTC market where the client is buying or selling directly from the market maker . AVA does not permit these practices on AVA's platform. AVA strictly forbids any form of manipulation of its prices, execution, and platform or making transactions based on errors, omissions or misquotes on the AVA platform. AVA reserves the right to investigate and review any account AVA suspects of manipulation and withhold funds suspected of being derived from such activity. AVA reserves the right to void any transaction which it has determined to be a result of any of these practices and will have no liability to the customer whatsoever for any losses incurred.'
Basically this means that they can (and will) cancel all your profitable trades with durations less than several minutes, and you're left with the losers, to the extent that your whole account may be wiped out. Just look at FPA, there's plenty of cases of wannabe smart arbitrage guys who got their profits withheld.
If you - as you claim - use arbitrage, you're either not profitable, or your profits are too small, or you haven't tried withdrawing yet. Anyway, enjoy why it lasts. By the way, ever asked yourself why the MFATA account was stopped?
Very strange: No active real account beside the price of $800. If you sold just 1 piece - you are not prepared to invest few hundred of dollars in real account? Can you imagine how your sales wouldl explode? Or it is too risky for you even? -And this is just another not really working EA? Looking at your MLPS poor statements potential clients can imagine this is just another scam, sorry.😭
