How to check last high or low value on stochastic using while loop

Why do you need to check it in a while loop? What's your logic or what are you trying to accomplish?

Like the user above, I'm unsure as to why you require it to be a while loop. 

There are many options for what it sounds like you're looking to achieve.

The second statement in a for loop is a boolean check, for example you could do something like this:

bool found = false;

for (int i = startIndex; !found; i--)
{
	if (stoch[i] > 95 || stoch[i] < 5)
		found = true;
}

Ideally, you should identify the bounds of the loop, but you can combine that check:

bool found = false;

for (int i = startIndex; i >= 0 && !found; i--)
{
	if (stoch[i] > 95 || stoch[i] < 5)
		found = true;
}

However, if you really do require it to be a while loop, here's a simple example:

bool found = false;
int i = startIndex;

while (!found)
{
	if (stoch[i] > 95 || stoch[i] < 5)
		found = true;
		
	i--;
}

Just be cautious to not get stuck in an infinite loop, or access invalid indices from collections.

May i know your telegram please. When condition goes true it only take value one time. And it resets value to 0 and not continiuosly gives last data value.

I need to know continuously every tick or bar what was last overbought or oversold point.

I need to know continuously every tick or bar what was last overbought or oversold point.  

What I would consider doing then is:

1) in your OnStart do the while loop and find the last overbought/sold

2) create a class variable and store the index of the last overbought bar index in it

3) for every onbar event, check the stoch. If it's overbough/sold, update the global variation with the new bar number.

When you want bots running fast to respond to the market,  so no need to execute a loop every single time a new bar or tick occurs.
