Target price conversions are a way to program a future transaction (buy or sell) based on a target price for a given crypto currency. You can now program to buy crypto at a lower price, or program to sell once an asset you hold rises to a certain price. That way, if the market reaches your target price, your pre-set transaction will be executed automatically, and if it doesn’t, then your transaction will not happen.
However, it's important to note that the execution of the programmed conversion is subject to real market conditions and there is no guarantee your target price will ever be met.
