If
Used in combination with Then to form a conditional statement that executes specific instructions if a logical expression is true, and with Else to form a conditional statement that executes specific instructions if a logical expression is false.
The conditional execution statement must contain both If and Then; Else is optional.
Begin and End statements are used to group instructions for conditional execution; a Begin must always be followed by an End.
Begin should not be followed by a semicolon (;), code lines within an instruction group should end with a semicolon (;), and only the last instance of End within the same conditional execution statement should be followed by a semicolon (;).
Usage
If E Then I1 Else I2
or:
If E Then Begin
I1;
I2;
End
Else Begin
I3;
I4;
End;
Where: E - a true/false expression
I - conditional instructions
Example
If UpTrend is false then sell:
If UpTrend=False Then Sell Next Bar Market;
If UpTrend is true then buy, otherwise sell short:
If UpTrend Then Buy Next Bar Market Else SellShort Next Bar Market;
If UpTrend is true then buy, otherwise sell short:
If UpTrend Then Begin
