So it turns out that externally I can't change the contents of a condition that, when checked, executes an expression.

Is there really no way to do this?

If you don't like something in the predefined function itself, you should write your own.

I have described the method to you in detail.

2) An external variable is a constant and cannot be initialised by an expression.

You can, but it is better not to do so. You can get confused later. It is a variable just like all the others.

No way, it's technically a constant, and behaves accordingly.

You can assign any value to an external variable in your code.

Try this:

extern int Param = 1234;

void start()
 {
  Alert(Param);
  Param = 4321;
  Alert(Param);
 }

Hello,

I am making a buffer for a price.

double open[5];
int start() {

Specified what to show - it shows normally.

open[i]=max2;

But all 5 readings are the same - I want to write the 5 last readings.

ArraySetAsSeries(open,true);
for(i = 1; i < 5; i++){
open[i] = open[i-1];
}

I don't understand what else needs to be done?

You can, but you can also re-define the constant.

Define and constant are not exactly the same thing.

A define is defined and initialized at the preprocessor level. It does not change during operation. It is hardwired into the code.

A constant is, in other words, a variable which is initialized once per one block call. In the process the constant can have different values.

In our case, an external variable is an ordinary variable with a manual initialisation option.

How can one value be higher and lower than another at the same time

maybe || (logical OR) should be written instead of && ?

I have a question. If for example a series of BUY trades has a profit factor -1.01, then it would be better to open a series of SELL trades with parameters reversed. i.e. if buy take was 200 pips and stop 100, then buy 100 and stop 200 for SELL? Am I thinking correctly?
