thankyou for your work expertlive. I am having trouble getting it to load in the platform successfully.

I unzip it into the indicator folder but it doesn't appear when I restart the platform. I'm not sure why.

Could you please just attach it or post the code here directly without zipping and maybe that might work?

Is this supposed to go in the experts folder or the indicators folder? Does this actually execute buy/sell orders or is this just the indicator?

It is clear from the image you posted that you understand what I'm trying to do here. Keep the program within the channel. Do you know how to program it to do this?

that works great expertlive, thankyou! Could you modify this indicator the same way? I think I like this indicator more than the shi even though they are so similar, this one seems more stable to me. Can you instruct me in how to make the modified indicator part of an EA so I can backtest it? or could you do it? I would like to add this as a filter for these two EA's (see attached)

the .gif image shows the difference in the two on a chart. The number of bars this looks at changes how it moves in the chart too. what language is shi showing on the chart? Could it show english?

On the EMA CROSS I don't just want the stop loss set at the filter level I don't want the EMA CROSS to open a position at all which would have to close outside the channel. That would depend on the TP goal but that's how I'd like the filter to work on the EMA CROSS and on the 'whatever' EA.

I admire your ability to program I wish I knew how to do it more.

Yes works good in the back tester, but is better in timeframe of 4 hours. I wish understand the logic of the tigger

It works good in metatrader back tester

.

Note: The back testing optimized for the maximum accuracy results.

I too, would like to know what triggers this EA, using laymen terminology. I have tested this, but found that it would buy for no apparent reason. Why? I tested this live too on Interbank.

Can someone please describe the logic of this EA in laymen terminology?

Fisher · #**667** (**permalink**) 08-10-2006, 07:39 PM

anyone can code a program to give sound alert when ema crossing?
thanks.

rodrigokaus · #**668** (**permalink**) 08-14-2006, 10:10 PM

Becouse this EMA Cross is slowly?
The system don´t open the positions ecxatly when the moving averages crosses. Is it possible?

Thanks

The Wise Trader · #**669** (**permalink**) 08-14-2006, 10:32 PM

I'm finding that it will take a long or short position, but it's not based on when the EMA crosses. I have it set for the default, 1 and 5, but it will take a position for no apparent reason, even if it does not cross. I don't understand the logic behind it, or why it takes a trade when it does. I've even seen it cross and watch it NOT take a trade one way or the other.

Can someone PLEASE enlighten me on this one?

Hi Wise!

I have a very bad memory!

could you tell me what's the version of the EA you are talking about? and please attach it in your reply to check it.
Now, I have the time to return to the EMA CROSS and the forum!
