How is it possible that my graph does not correspond with another person's graph?

If you have invested in a bot, then the bot will immediately begin working, but this does not mean that it takes a position instantly.

The bot analyses the different trading prices and waits for the right moment to take a position with all people who have invested in the same bot.
It could be that one person acquired a profit, but the other person acquired losses. These potential profits or losses are dependent on the moment when you start a bot. In short, both users can be exposed to the same bot, but not to the same trade.
Imagine that the bot you have started did not take a position at the moment, then you will see a graph of the trading prices of two currencies, such as BTC - USDT or EUR - USDT.
It depends on the bots which currencies it concerns, and you can find this at the subheading 'Information' and then 'Market' when you press on a bot. Because of this, it might look like the active bot has taken a position when the graphs are fluctuating, but this does not have to be the case.
