iADX scripting question

I'm just starting to learn writing EA script. So, forgive me for such a newbie question.

I'm using iADX. And part of my code:

[script]

CurrentADX = iADX(NULL, 15, PeriodADX, PRICE_CLOSE, MODE_MAIN, 0);
PreviousADX = iADX(NULL, 15, PeriodADX, PRICE_CLOSE, MODE_MAIN, 1);

// BUY
if (CurrentADX > 25 && PreviousADX < 25) {

// other script

}

[/script]

Image attached is created after I run the script tester. You can see that BUY order opened on 2008.05.08 03:18 at price 204.80 (#1), and it was closed by 30 stop loss at 204.50 (#2) -- Highlited.

My question is:
Vertical Navy dashed line marked 03:18, when the order placed. And horizontal navy dashed line is the price when order opened.

1. My condition is to open an order when CurrentADX (LightSeaGreen line) is more than 25 level. But, in the image we can see that ADX line never crossed 25 level. How could this happened?

2. The highest price at that bar is 204.73. Why order opened at the 204.80?

Thanks in advance.

mainly due to using a candle that hasn't finsihed. By using 0 you have selected the active candle, it is possible for it to move up enough to cause the 25 level to trigger and then fall back down lower so it looks like it never hit the 25 level. A better way is to use 1 and 2 for your selection, this will ensure that you only select candles that have completely formed.

Thanks magnumfreak,


Just a thought, what do you think is better, move back 1 step (0 -> 1 and 1 -> 2) or using PRICE_OPEN as the applied price in the iADX's parameter? Thanks again.
