Change PRICE_OPEN to PRICE_CLOSE that should help the repaint issue.

Hi,

I'm writing a basic EA that initiates a trade based on the 8 and 13 EMA crossing on H1.

When I backtest this I see that during certain periods, the lines crossover and re-crossover giving false signals...basically price is trading up and down in a tight range and causing the crossover signals to fire.

As you know, the MA crossover works best in a trending market, not when it's bobbling up and down and not going anywhere.

See attached chart for an example of what I mean...between the blue vertical lines I have marked 5 'X' spots where the lines crossover.

Is there any indicator I can use to add to the existing EA MA crossover signals system to prevent entering a trade during times when price is whipsawing up and down. How can I 'programmatically' tell when not to enter a trade during these conditions?

Cheers,
Jenks.

Hi all,

Will this EA(EMA_CROSSmod.mq4) recognize if a trade has not been closed while the computer was turned off because of an electricity outage or internet connection problem in my area? And will it be able to resume the same trade?

Regards,

Hi guys,

i downloaded a simple Moving Average Price Alert here some time ago.

Unfortunately i'm having trouble getting the alert to play a custom sound (i.e i cannot choose my own wav sound file); the indicator simply keeps defaulting to the standard alert.wav file in the MT4 sounds folder..

can anyone help??!? im going crazy, cant seem to figure out whats wrong with the code!!

code below (and attached)

Hi

I been looking for an EA that can follow this system. But so far
without any success. So let me explain how it works and it sure
works very well.

Pair: GBPUSD
Time: H1

EMA: 7
EMA: 14

SELL:

7 moves below 14. No wait for at least 1 candlestick to be below the cross
where high low price is clear of the EMA's. Can't touch. Upon next retrace,

and price at least break any of the EMA with 1 pip. We enter short.

The filter here is the clear candlestick. Stop Loss is 100 pips and take
profit is 100 pips. BUT when 50 pips has been gained move stop loss to
break even (Entry price). Or activate trailing SL 25 pips.

Buy:

7 moves above 14. No wait for at least 1 candlestick to be above the cross
where high low price is clear of the EMA's. Can't touch. Upon next retrace and price at least break any of the EMA with 1 pip. We enter long.

The filter here is the clear candlestick. Stop Loss is 100 pips and take
profit is 100 pips. BUT when 50 pips has been gained move stop loss to
break even (Entry price). Or activate trailing SL 25 pips.

When EMA whipsaw there is normally no clear candle. A filter
who with x pips between EMA lines would be good as well. But
is not required.

Is there any EA available like this or can anyone code it?

Thanks,

Daniel

Sorry for me English..

I try several experts (mq4) EMA which I download from this forum but I have always the same results.. There are good but when I see Open chart, sometimes I see another order (for example when ShortEma(10)<LongEma(90) is realized BUY order, not SELL).
I don t know where is problem because I tried to simulate a lot of experts and always the same results. Experts usually work correctly but I always see some mistakes.

Hi Daniel:

Thank you for posting this entry method.

From brief backtesting I can't find much use for the 14ema at entry. Seems the candle always pulls away from the 7 with no need for the 14ema. However, the 14e may help with deciding to stay in the trade.

I know a professional who scalps similar to this entering when price breaks beyond the pulled away candle and stays in as long as next candles are pulled away from the ema.

Steve
