Before using trading bots, you need to understand that they are NOT a surefire profit machine. You may want to watch this video.
Pro API keys do NOT need deposit/withdrawal permissions
API keys are the "keys" to access your trading exchange account with a 3rd party app. If an app has withdrawal permissions, it can theoretically steal your crypto. This bot does not need such permissions to work, thus it can lose money if not configured properly, but it can't steal your money.
Pro Configurable sell stops, buy stops, and trailing profit stops
Stops are automated orders to protect your capital (by selling or buying) if the market behaves unexpectedly. They let you leave with most of your capital if things don't go your way. Trailing profit stops protect your capital against market crashes while at the same time "letting the ball roll". They get activated by sudden drops of price, and their activation levels rise automatically with the price of the asset.
Pro Simulator for backtesting strategies
Backtesting is basically running a set of rules on past market data and seeing how the bot would have performed during that period. With good projection, an experienced trader can always find similar market conditions to the current ones in past data and then carry out that winning strategy on to the future.
Pro Fully automated "technical analysis" based trading approach
Technical analysis is about interpreting the chart action in a way that allows a trader to single out statistically "high profit-low risk" trades.
Technical analysis based trading bots do not open trades based on a static matrix, instead they have some adaptability to changing market conditions.
