Help me to Find the Most Efficient/Best Code in Variables Declaration [100+ Variables]
What about an array?
..
int start() {
arr[0] = iRSI(..);
arr[1] = iRSI(..);
...
}

I have more than 100 variables declaration inside start(). Here's my example:

int start() {

That will change nothing if we are talking about execution speed.

Should I put all variables in one declaration? Like this:

Local declaration will use resources of your processor.
Global declaration will use resources of your Random Access Memory.

Should I put all variables in one declaration? Like this:int start()
{
double a, b, c; // variables 1 to 100+
a = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
b = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
c = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
return 0;
}
Should I declare it global? To avoid excessive declaration in start()
double a, b, c; // global variables 1 to 100+
int start()
{
a = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
b = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
c = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
/*

return 0;
}
- Globally declared if they have to be shared between routines.
- Statically declared if they have to be remembered between calls.
Don't declare them and then initialize them - that's bad style. Do both at once double a = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
double b = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
double c = iRSI("AUDNZD", Period(), 14, PRICE_CLOSE, i);
Then you might as well as use arrays.How are you going to access them? if(i == 1) do_something(a);
if(i == 2) do_something(b);- For efficiency, don't do per tick what you can do per bar. If you're waiting for price to reach a level, remember the level and ignore ticks until you reach it (or you reach a invalid condition or new bar.)

No.
I want to declared different variable names for each currency pairs to make it easy to read/maintain.

Could you please elaborate more on this? 1-5.
I use the variables for counters to use in some calculation then use it to buffers. I don't use this variables to hold the values for longer time.
