You are price delay (lag) trading. This type of trading is predatory and hurts brokers who provide market making services (have dealing desks.)
Put simply, if the broker's price feed is delayed and there's a difference between actual market price and the price feed, you are exploiting this delay (lag) for profit at the broker's expense. The broker can't hedge your position when they take the other side and is left with the price difference as a loss.
This is why your duration is measured in seconds.. this isn't scalping..
This type of trading does not work on an ECN or STP type broker.
During the last two contests, the few people who tried this were disqualified.
In the real world, live accounts get shut down for this. When you're found out, your initial deposit is returned to you (if you're lucky) and you are unable to take out any profits. Any broker who pays out profits on this type of trading will soon be out of business.
Honestly, it's trash like you that makes these contests annoying to spectate. Do you realize what message you're sending to new traders who see your stats?
Never trade for the sake of trading. Instead, wait for the trades where you have a clear advantage and exploit it.
