SMA outside BBs indie?

[5iver]

I was hoping someone could help me build an indie that put up a simple visual alert when a 50sma travels outside the upper/lower bands of a 1.9/20 period Bollinger?

It seems like it should be quite simple, but already my coding skills are failing me... I can see how I might do it as a Strategy, but not as a simple indie.

Any ideas greatly appreciated.

Hi 5iver, hopefully this can get you started:

if (SMA(50)[0] > Bollinger(1.9, 20).Upper[0])
    DrawArrowDown("down arrow" + CurrentBar, false, 0, High[0] + TickSize, Color.Red);
else if (SMA(50)[0] < Bollinger(1.9, 20).Lower[0])
    DrawArrowUp("up arrow" + CurrentBar, false, 0, Low[0] - TickSize, Color.Green);

Very kind and very speedy Austin, thanks.

I'll have a go at making this into a functioning indie. My coding skills are at the sub-neanderthal level... but I'll have an honest crack at it. Thanks again.

OK, I can't make it work, I'm such a dunce.

It maybe easier doing this in the Strategy Wizard and then 'unlocking' the code to port it over to an indicator, this way the conditions are setup to work out of the box....

Didn't know that was an option. Thanks :-)
