Hi ! unfortunately I can not specify the earnings for you. announce! Despite receiving the alert by Telegram and having my brokers online, I never managed to buy at the price you buy. indicate.
This is almost always the case and the last example I register is with AGRO, it was indicated that it should not be bought for more than $ 12 at 11:36 am and I look at the brokers and it is already at $ 12.80. The same happened with Teco and previously with other recommended assets.
Is there a way to solve it? Thank you
