using a bot can help us to trade like pro trader but remember, if we don't have experience or have any knowledge in trading, then its the same like suicide with our money and we can not take control for the bot. but if we want to learn to be pro trader, then i think we don't need to use bot and we can trying step by step to increase our skills in trading.
Using bots can restrict your command on the trade and if the market goes reverse then this bot trading will become loss. I only do manual trading and i use to place the order what rate i want to sell and buy so like this my orders get cleared even if i am live or not.
