Build script
Coder's Guru
I've tried searching the various forums of the Net an expert or a script to issue pending orders with a specified time in order to operate in "News". Got some but have not been satisfactory. I tried to make an EA that did not work and can not identify the failure. I tried to make a script to add the chart but could not succeed. I tried to modify a script's standard MT4 also without success. I wonder if you can help me build a script for this purpose ... Issue orders pending buy and sell at pre determined time.
thank you,

Help Needed In Coding A Trendline-Pullback/Retest Indicator Plus With Alert
Hi traders, is there anybody here who can help me to code an indicator which is able to mark out a proper trendline/channel, followed by a breakout alert (if there's any) and alert us when there's a pullback on it. The pullback can also be a retracement to the 38.2%, 50% or 61.8% Fib level. I need something which can mark out a proper trendline/channel cause I feel that most of the auto-trendline or auto-channel indicators are not marking out the proper line. I've been searching high and low in most of the forums but could not find any of this so-called trendline pullback indicator. I've tried DeMark but I'm not really comfortable in using it. I'm not sure whether this indicator is possible to code. But I believe that nothing is possible in this world. Cheers...
Hi Blackwood
If you have a profitable EA, I'll code it for you or let you know if it's really beyond my ability.
With reference to post #148, is it possible to code an EA? If it can be done, I believe the EA can be used for scalping... Do try to work it out, yeah.. Thanks in advance..
Need help remodel EA
Hi ....
Anyone willing to help me add the HH and LL in H1 to show trends in EA below and change the red line and blue to Supplay and demand in H1? I found this on the EA forums and I modify it but not perfect. I want this EA works based Supplay and Demand to see the trend by using the HH and LL. I hope EA can be an entry from the M5 with a yellow Supplay Demand and Demand Supplay refers to the red and blue in H1 (red and blue are now false, not Supplay and Demand, Please be modified into Supplay and Demand). Trend and reversal of form we take the form of HH and LL series in H1.
Thank you.
Please tell me how to make an entry after Take Profit:)
Hi,genius coder & kind people:D
Now I'm developing a simple EA but can't understand below conditions.
If previous position is closed by Take Profit,make new entry that set 20 pips by s/l and t/p at next open price.(on 5M chart)
I tried to write one.
if(OrderSelect(1,SELECT_BY_POS,MODE_HISTORY)) //Last position was instant order OP_BUY or OP_SELL
{
if(OrderClosePrice() == OrderTakeProfit()) // IF close price is the same with take profit price
{
if(OrderType() == OP_BUY) //That order's order type is buy
{
OrderSend(OP_BUY,Lots,Ask,Slippage,SLpips,Ask+20*Point,"",MAGIC);// Lots and other variables is defined by my self
}
else if(OrderType() == OP_SELL)
{
OrderSend(OP_SELL,Lots,Bid,Slippage,SLpips,Bid-20*Point,"",MAGIC);
}
}
I tried many time run by Strategy tester,but can't action as I'm hoping.
Some body give me a help from this question!!
Regards.
