Thank you for the warning, I'll pay more attention now to the charts. On the other hand I myself have certain doubts here. Even though my trading experience is not that huge at the moment, I've done over 100 trades on my real trading account with Olymp so far. I use 1 minute timeframe and 1 min options expiration time. Only once I ran into a situation when the option expired exactly at the price of an opening. In this case Olymp refunds the cost of option and you neither gain nor lose anything. Most of the times price goes far enough to be quite sure whether it's a win or loss. Might depend on how strong are your entry points though… Anyway, how often can you run into a situation when the price will be THAT MUCH close to your entry point?For Olymp Trade wise, they are more active in manipulating closing price when you trade binary option with them. I have encountered this issue multiple times (at least 5) and taken some screenshot of it. When you are winning in binary option by about 0.2 pips (+0.2), you would suddenly become lose at the last 1 second by 0.1 pip (-0.1). The next second, the price would go back to normal, so its like a 0.3 pips price manipulation. I have done comparison on the price between Olymp Trade and IG. At the time of entry, both providers show the same price. Only at the sudden last second of closing, price would differ by up to 0.3 pips. Beware of this guys!
Not sure about their forex as I didn't trade with them on forex.
