Again, welcome to the basic series of SQL (Structured Query Language) tutorials. This article describes the instructions that database definition language (DDL) uses to create databases and tables, and to modify the results of a table.
Be careful when you use these instructions-it's easy to delete the main structure in your database so that you lose data. So, before you start modifying the database, you need to know what the database is.

The follow set is for non-Terminator. Follow (u) expresses the set of all possible terminologies with non-ter

2. Repeated transmission: to the shape into the u->p ... Production (where p is non-terminator), the entire contents of first (p) should be transmitted to "U", meaning that it is only necessary to pass the initial set of non-Terminator to the past-this place is a place to pay attention to, but also difficult.

The current price has been moving towards profit, but before the expected profit movement is completed or falls below a local bottom, the market operation has given some dangerous signals, in this case, it is necessary to actively end the entire transaction to lock the profit. It can be seen that, unlike protective stop loss, follow-up stop loss is designed for short-term profitable transactions and may sometimes end at a medium trend or even the top
