Boolean log with integers

[jeremymgp]

Hello,

I'd like to find a work around for doing Boolean operations on integers.

When a short-term and long-term SMA are rising, I'm doing something. However sometimes when the longer-term SMA turns to rising, the short term SMA is in the middle of rising.

I don't want signals where the short-term SMA is in the middle of a rise when the longterm SMA turns to rise. I only want full signals where the short-term SMA turns to rise while the longterm SMA is rising also.

So I'm creating logic that:
- checks if the longterm SMA has turned to rise & the shortterm SMA is NOT rising at the turn:
- sets a value to 1

For example:

if (SMA(200)[0] > SMA(200)[1] && SMA(200)[1] < SMA(200)[2] && SMA(14)[0] < SMA(14)[1])
{
value = 1;
}

if (value = 1 && SMA(14)[0] > SMA(14)[1] && SMA(14)[1] < SMA(14)[2])
{
do something;
}

Value stays at 1 until longterm SMA changes direction, then recalculate.

----

Trouble is I can't use "value = 1" with "&&" Boolean operators. With some languages just changing the "&&" to "&" works, but this didn't happen either.

Is there any way I can work around using Boolean logic with integers?

Thanks,
Jeremy

Please try
if (value == 1 ...
(2 '=' signs!)

Thanks for your patience with my learning curve.

I'm trying to detect SMA turning points - what's the best way to do this? I'm using the logic:
"if current bar[0] > previous bar[1] && previous bar[1] < previous bar [2]" then it's a turn.

So far no luck. I've tried using Rising()/Falling() but am unable to access previous values, eg.
if (Falling(SMA(60)[1])) doesn't work.

I've also tried logic such as:
if (SMA(200)[0] > SMA(200)[1] && SMA(200)[1] < SMA(200)[2])
{
do something
}
but the "do something" doesn't happen.

Thanks for your help,

Jeremy

You want to do:

if (Falling(SMA(60))
     // Do something

In order to access previous returns on this you could try saving the values in some temporary bools.

For your code:

if (SMA(200)[0] > SMA(200)[1] && SMA(200)[1] < SMA(200)[2])
{
     // Do something
}

I don't see why it wouldn't work. If the "do something" isn't executing then it is simply the condition hasn't evaluated to true. For your "do something" just place a Print line to see what is going on. Also print out the values of SMA(200)[0], [1], and [2] before the if so you can manually check it out.

It's the barsAgo that seems to be doing it. I'm setting background color as follows:

if (SMA(100)[0] > SMA(200)[0])
{
BackColor = Color.PaleGreen;
}

and green bars of bgd color appear throughout the chart.

As soon as I change it to:
if (SMA(100)[0] > SMA(200)[1])
however, there's nothing.

How can I apply logic using barsAgo to a whole chart, not just the present bar?
