We buy trading signals for stocks, currencies, and derivatives. In order to sell us your signals, you need to purchase a bot whose job is to generate the signals on your behalf following your instructions. If you don't give your bot any instructions, it simply generates a buy signal when prices are low and a sell one when prices are high. After generating the trading signals, your bot then sells them to our trading system. Our trading system, which is a bot itself, then pays your bot a dollar amount that depends on how profitable your trading signals are. If our trading system makes a loss trading based on your bot's signals, it demands and receives a few cents and in rare cases dollars from your bot. As such, you will observe your bot's cash proceeds fluctuate throughout its lifetime. Your bot's life ends when you decided to Cash Out the proceeds it has generated. After that, you can purchase another one if you want. To see how all this works, we recommend selecting Bot v1 and then "Free Trial."
