# How to get the EA to realise the previous bar has closed above the BB?

9

Hi everyone,

I'm trying to get the EA to record when a bar closes outside the bollingerbands, then initiate a trade if this happened in the previous bar

and the ema's cross or something. My code so far looks like this:

int bar, sll;

if( Close[0] > bollingerband ){

bar = Bars;}

if( bar+1 == Bars){

if(ema1>ema2){

sll = 1}

if ( bar+2 == Bars ){
bar = 0;}

Unfortunately this doesn't seem to work and Ive also tried making it a static as well as a global variable. So I would be most grateful if someone could point me in the right direction

1. ```int bar, sll;
if( Close[0] > bollingerband ){
bar = Bars;}
if( bar+1 == Bars){```
Since bar is not a static or global its value can ONLY be zero or Bars. Therefor bar+1==Bars will NEVER be true.
2. when a bar closes outside the bollingerbands
```int start(){
// Wait for the start of a new bar.
static datetime Time0; if (Time0==Time[0]) return(0); Time0=Time[0];

// Check for close outside BB
if (Close[1] > bollingerband){ ...```

 tasaoirse: its nt working..could u plz code it a right way which works perfectly "Doesn't work" is meaningless - just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires - meaningless. There are no mind readers here.
