Help With labels

could some one guide me on getting the labels to show

I changed the indicator to show futures and i tried but cant get the labels to work, I am very new at this. It is difficult to use just the ticker on the futures

I would like to input a label to show like

ZGG9 Gold 767.6 etc.

One line not two

I need one line ont 2 in the indicator so it would be (WPR + RSI)/2

thank you

 

need help on testing a EA

Hi, I get a EA which is reported to generate very good profit and I want to test it by using it the strategy tester. But the EA would only generate alerts, not doing any trades. I am a newbie to programming in MQL. Can anybody give me a hand on highlighting what parts of the code I should change in order to enable testing and give me some hints on the changes to be made? I have read the tutorial by codersguru but I think I understand it. But that is all.

Below is the source of the EA. A triilion thanks in advance:

#property indicator_separate_window

#property indicator_buffers 5

#property indicator_color1 Yellow

#property indicator_color2 LimeGreen

#property indicator_color3 Red

#property indicator_color4 Yellow

#property indicator_color5 Cyan

#property indicator_width1 2

#property indicator_width2 2

#property indicator_width3 2

need some help

can anyone give me the code for adding set trading times to an ea as i only what it to trade for a few hwers a day, not all day

thank you all for your help

This is an indicator, not EA. Indicators can't open and close orders.

If your time from 10am to 5pm, put this string at the beginning of start block:

if (TimeHour(TimeCurrent())=17)return(0);

 

thanks roger

so I need to check for ways to convert indicators to EA, right?

btw, can anyone tell me the main idea of the indicator?

 

Is it right

thank you so much, is it in the right place , where I put it.

//+------------------------------------------------------------------+

//| expert start function |

//+------------------------------------------------------------------+

if (TimeHour(TimeCurrent())=17)return(0);

int start() {

int Order = SIGNAL_NONE;

int Total, Ticket;

double StopLossLevel, TakeProfitLevel;
