The thing is that the quotes in your trading terminal may differ from ours a bit. This has to do with the fact that brokers work with various liquidity providers with different quoting. At the same time, some of them include the spread while others don’t.
Still, this shouldn’t distract you from trading since despite the difference in quoting, the price tends to move in the same direction. Your goal is to get the signal and open at the current market price in the same direction (unless the price has gone to far away from the entry point) and with the same expiry time. We do not provide scalping signals, which is why the space is almost always enough to reduce this difference to nothing and get the same results that we do.
