When working with the mathematical functions, you must observe the function precedence, i.e. the different functions bind to different degrees.
|
+, - (Unary, i.e., sign), Not |
Highest binding |
|
, /* |
|
|
+, - |
|
|
<, >, <=, >=, =, <> |
|
|
And |
|
|
Or,Xor |
Lowest binding |
The "+" and "-" signs and the "NOT" function bind most strongly. This is followed by the operators that link two numbers; here, dot before dash applies. OR" and "XOR" have the weakest binding.
The property notation point always takes precedence over the functions mentioned here. If a formula contains two operators with equally strong bindings, the expression is processed from left to right.
As in mathematics, you can override the hierarchy with round brackets:
High+(Low/2) corresponds to High+Low/2
(High+Low)/2 corresponds to High/2+Low/2
Close>Open And Low*1.05>High corresponds to (Close>Open) And ((Low*1.05)>High)
Use round brackets to join parts that belong together if you are unsure of the precedence. This avoids errors and makes the formula easier to read.
