#事件合约 Exposing the Scam of Selling Indicator Contracts. Recently, some bloggers have been promoting ads for selling indicators in the square, along with a series of screenshots showing profits that have driven many traders into a frenzy, unaware that this is all an illusion. First of all, their indicator signals can be added later and temporarily deleted, so the winning rate should just be taken as a joke. Moreover, the authorization fee of up to 300u and the monthly renewal fees for the indicators are truly harmful. Anyway, I've already fallen into this trap, so everyone, keep your eyes open and don't get scammed again.
