}[/CODE]
Above is the code for the indicator. Simply, it draws a line that should be updatable via the EA using the intiially mentioned code:
[CODE]temp = iCustom(NULL, 0, "AntariaRising", 200, 1.2, 0, 0); //temp not used. Function returns a doubleI guess I want to replace the final piece of code that actually allows me to update into the incicator object the variable that its tracking on, so that I can later use it as a stop-out line. The remaining code is irrelevant however. When I run the above function i expect antaria to move position from 1.39 or whatever it starts on, to 1.2. I can't remember if I use the 200 variable. I think I've chopped out my header and footer comments, but the entire slave indicator is up there, which is AntariaRising meantioned in immediately above code
this was the only function I could find that talked to indicator objects, and I use it to read off values in other areas.
About your indicator code. It's wrong.
Var. limit equal zero ever.
Take off the string:
int limit;
from the start().
Help me with this code pls
i want someone to help me with this code it open trade when i want it but close it automatically so i want it to trade with stop loss not closing when not crossing again this is the code

//+------------------------------------------------------------------+thanks roger09 God Bless you
Thanks Roger, I've removed that second limit declaration from my start function. I'm surprised the compiler was allowing that one, but it hadn't impacted my program noticably.
Still I am unsure how to alter the running instance of that indcator from my EA. A method would be much appreciated, or at least confirmation that the API does not currently allow me to pass information to running indicators.
Thanks.
I start this tread for getting some help here.I am learnig to code for the indicator attached .however it did not work out.Could anybody help? It is a very reliable indicator and if somebody could make a EA for it .it is almost a holy grail.tia.
Basic priciple is:
1.open Sell position when red arrow appear,
2open buy position when white arrow appear and automaticly close all th esell position/positions.
3.apply for any timeframe .
4.no stop loss,
5.add order function.
Loking forward to response!

George's Oscar Calculator - Can anyone code an indicator for it?
Hi Folks,
I don't know if anyone is familiar with Forex Made-EZ by George Smith.
I'm currently reviewing his work and wondered if anyone has coded an indicator for the Oscar oscillator he uses?
The formula is
let A = the highest high of the last eight bars (including this one)
let B = the lowest low of the past eight bars (including this one)
let C = current bars closing price
let X = the previous oscillator figure (Oscar)
Today's "rough" oscillator equals (C-B) divided by (A-B) times 100.
Next we "smooth" our rough number (let's call it Y) like this:
Final oscillator number = ((X divided by 3) times 2), plus (Y divided by 3).
If anyone has either coded this or can code this it would be highly appreciated.
Regards Steve
Inverted Trailing Stop
Hi,
I want some help with an idea.
I'm using trailing stops on my EAs (3 step trailing), but I want to do the inverted thing to protect losses.
I will try to explain:
I open an order, with a initial stop loss.
If the trade go 15 pips in loss direction and come back 10 pips, close the trade (first step).
If the trade go 30 pips in loss direction and come back 15 pips, close the trade (second step).
Something like this.
Thanks for the help

So, the losing trade closing always need to wait until it bounce back right?
How about if it doen't bounceback?
Will we close at the intial SL?
