If a person buys a program, he has had the experience to know when to intervene and when not to. Intervention, when not needed, can turn a winning strategy into a losing one, and vice versa, when not intervening can quickly deplete a trading account. Some people think that using a stock robot eliminates emotions in trading. Unfortunately, it is not. While the program does not have emotions, the person running the program is able to feel. A person may be tempted to intervene when he sees that the algorithm is losing money, but the program can still function effectively (losing trades happen). Or a person may step in to take a profit prematurely by manually closing the trade when he sees a profit he likes.

All of these emotional activities can destroy profitable robot strategies in the market. Exchange robot strategies Exchange robots can use dozens of strategies. We'll look at a few of the main ones: • scalping: a trading session with a limited duration. For example, no more than 30 minutes or several hours. The algorithm uses the maximum price spikes by creating an order with take profit and stop loss parameters. This strategy is based on Bollinger Bands; • trending: trading over long periods of time. The bot buys when the price goes up or down.

Also, trend trading is possible with "reversals" of quotes. The more indicators the robot uses for trend trading, the more efficient it can be; • grid: formation of pending orders on the basis of X% more and less than the current price. The result is the so-called "network". Effective with strong trend fluctuations, but during the flat period, the grid strategy carries great risks. There are also many other strategies applicable to specific markets and time periods. An exchange bot can carry several strategies “on board” at once. .
