TimeStart Code??

[Kenny]

Hi there,

I am trying to learn the coding of MetaEditor4.

I have an EA from my friend and I am trying to learn each lines one by one.

Currently EA doesn't place as many trades as it did, and I found the reason was because of TimeStart code in OrderSend, below is the relevant coding of the packet:

On top:

extern int TimeStart = 0;
extern bool No_Open = false;
bool EntryLimit = false; 
int i, ticket;

Body:

if(No_Open == false && Hour() == TimeStart && EntryLimit == false)
     {
      ticket=OrderSend(Symbol(),OP_BUY,LotsOpt(),Ask,10,0,0,"abc",Magic+1,0,Blue);
     }

I found if I remove "Hour() == TimeStart", EA starts to place many trade as it used to. But if I leave it there it doesn't.

I want to know what is the reasoning behind this TimeStart code? Is this to set a time to trade?

If so, why it puts on top as TimeStart=0? Shouldn't it specify a time range?

I tried to search what TimeStart do on Google with no luck. Can anyone help to explain what this TimeStart do?

Sorry I think I posted on wrong forum.. and it says I cannot create another post in next 6 hours..

It means the EA will trade only when the Hour is equal to 0.

The variable TimeStart is set to 0

So when the mql4 instruction Hour() is equal to  0 , the boolean operation   

Hour() == TimeStart 

becomes TRUE

And Hour() is equal to 0 only at 12 am i.e. every new opening Day

• FX opens 5pm ET Sunday and ends 5pm ET Friday. Some brokers start after (6pm is common/end before (up to 15 minutes) due to low volatility.

  Swap is computed 5pm ET. No swap if no open orders at that time.

• Brokers use a variety of timezones. Their local time (with or without DST,) GMT/UTC, GMT+2, NY+7.

  Only with NY+7 does the broker's 00:00 equals 5pm ET and the start of a daily bar (and H4) is the start of a new FX day.

  GMT brokers, means there is a 1 or 2 hour D1/H4 bar on Sunday (depending on NY DST,) and a short Friday bar.

  GMT+2 is close but doesn't adjust for NY DST.

  EET is closer except when their DST doesn't match NY's. Last Sunday of March and 1:00 on the last Sunday of October vs second Sunday in March and return at 2:00 a.m. EDT to 1:00 a.m. EST on the first Sunday in November.

• Non-NY+7, means the chart daily bar overlaps the start, and converting broker time to NY time requires broker to GMT to NY timezone conversions.

• If you search the web you will find differing answers. Those are all wrong (half the year) because they do not take DST into account (or that it changed in 2007 [important when testing history.])
