Different protection options in different strategies.
Trading methods have a few common protections:
Some methods will only buy once, other can buy multiple times. This is called "pyramid buying".
"Buy level" is a setting that protects against buying above the lowest EMA. The equivalents to this for margin trading are called "Long level" and "Short level".
Many methods won't place a strategy sell order below the break-even point, in some methods this is optional.
See the tables below for details about protections/constraints per method.
