Neosouvik: That's someone who used Exness ! ;) I totally agree with what you wrote.
About [Off Quotes], it's not even requotes as you can't accept another price, you just can NOT enter or exit. According to my experience, sometimes it's not too bad, sometimes it's just HORRIBLE.
About the screenshot you posted, you probably know that the graph shows the BID price, but you BUY (to close your SELL) at the ASK price. So Exness just widened the spread to NOT hit your TakeProfit (and probably manipulated a little the price too, so that it doesn't go down too much) because it didn't arrange Exness ... This is just a part of what they do HEAVILY !
