How do I set a flag for the following condition?

Hi,

When the condition arises where the Candle before has just closed across the 20MA from below to above it.

I would like to set a Flag called "FlagLowerBB" to False.

I initially declare it as bool FlagLowerBB = True;

What is the code for this and where do I put it to check at every tick to see when this condition arises and to set the Flag to false?

Why use flags?

What does the flag trigger later in the code?

The Flag will determine whether a Buy Condition is met later in the code.

There needs to be two different conditions that happen at different times before the Buy Signal is valid.

I use the Flag to determine the prior condition before the second condition comes into play.

Couldn't you just as easily put all the decision logic just before the buy/sell signal?

Like I said:

There needs to be two different conditions that happen at different times before the Buy Signal is valid.

The decision logic would only work if there was only one condition happening at one time.

I am trying to trade the bollinger bounce with my EA.

The BUY logic occurs when the price hits the lower bb (bollinger band).

The aim is to EXIT Buy when the price crosses above the upper bb.

But if the price continues to cut below the lower bb for two bearish candles, then Buy is Exited as a stop loss.

No more Buy Order Should be opened until the Price has Crossed back above the Middle BB.

FlagLowerBB is set to False initially.

When A Buy Order after price crosses below the Lower BB, The FlagLowerBB is set to True so that no further trades will be opened.

When the price crosses above the middle BB, FlagLowerBB is set to False again so that Buy Orders can be opened when the price goes below the Lower BB again.

This is the reason why I need a flag. How do I set such a flag properly?

I have managed to created a for loop that does this:

for (int x = 0; x < Bars; x ++)
{
if (Close1 > Middle1 && Close1 > Open1 && Open1 < Middle1)
{
FlagLowerBB = False;
}
}

But it slows down the backtesting speed.

Is this the only way to code it, or is there a more efficient way?

This code will now stop the loop if the flag is hit.

Thanks!
