Blue Star: There is a question worth exploring, If you set a take profit stop loss level, like yesterday when I doubled my three open positions, I set a protective stop loss for profit drawdown. Then the stop loss was triggered, and the profit increased from $3000 to $1300. And now when you look at the price, holding it can turn into a profit of $4000. May I ask, should we stick to the set of take profit and stop loss, or should we not set protective stop loss in the future? Group friend 1: Don't stop loss, meme. Don't stop loss, buy Danggui from scratch Blue Star: The contract I made yesterday Group friend 1: Then I don't understand, brother Blue Star: We should still adhere to taking profits and stopping losses, especially when doing contracts. Not setting stop losses may directly lead to liquidation Group Friend 2: This is only one example and does not have statistical significance. Let's assume that if it doubles now, 50% may lose back costs, and 50% may become a profit of 200%. Let's see which one you prefer Blue Star: Calculate which expectation value is greater, and then see everyone's wind direction aversion Group Friend 2: Alternatively, learn Meme and use high leverage on a per position basis, stop loss upon liquidation, and set up options such as doubling the capital or tripling the capital Blue Star: Meme, you won't worry about liquidation issues, there are leverage in the contract Group friend confession: It's a case of individual trading, and the margin is not interchangeable. You can only lose as much as you have in this order Blue Star: I am fully stocked Group Friend 2: Open a small account and try to close positions one by one, which is equivalent to automatically adding a -100% automatic liquidation
