Need an Explanation

[[Deleted]]

Dear All,
Can anyone explain to me about the following trading criteria (MQL4 Book - Simple Programs in MQL4 - Simple Expert Advisor), especially what is the meaning of "Distance between MAs "(double Rastvor = 28.0 / / Distance the between MAs),

Thank you.

//--------------------------------------------------------------- 5 --
// Trading criteria
MA_1_t=iMA(NULL,0,Period_MA_1,0,MODE_LWMA,PRICE_TYPICAL,0); // МА_1
MA_2_t=iMA(NULL,0,Period_MA_2,0,MODE_LWMA,PRICE_TYPICAL,0); // МА_2

if (MA_1_t > MA_2_t + Rastvor*Point) // If difference between
{ // ..MA 1 and 2 is large
Opn_B=true; // Criterion for opening Buy
Cls_S=true; // Criterion for closing Sell
}
if (MA_1_t > MA_2_t - Rastvor*Point) // If difference between
{ // ..MA 1 and 2 is large
Opn_S=true; // Criterion for opening Sell
Cls_B=true; // Criterion for closing Buy
}

Distance between MA is like distance between prices. If MA_1=1.54321 and MA_2=1.54320 then the distance between MA is 1_Point.

[Tjipke de Vries]

A Large DISTANCE is a definition you can make yourself

You can call 5 large but for someone else it has not be that way

In the code above the definition for large is when the VERTICALE difference between the lines is atleast Rastvor*Point

Rastvor has a value (28) and Point is also a value

1. Note that the meaning of Rastvor*Point is broker dependent. On a 4 digit broker it's 28 pips but on a 5 digit broker it's 2.8 pips. EA's must adjust PIP values.

   //++++ These are adjusted for 5 digit brokers.
   int     pips2points;    // slippage  3 pips    3=points    30=points
   double  pips2dbl;       // Stoploss 15 pips    0.015      0.0150
   int     Digits.pips;    // DoubleToStr(dbl/pips2dbl, Digits.pips)
   int     init(){
        if (Digits % 2 == 1){      // DE30=1/JPY=3/EURUSD=5 forum.mql4.com/43064#515262
                   pips2dbl    = Point*10; pips2points = 10;   Digits.pips = 1;
       } else {    pips2dbl    = Point;    pips2points =  1;   Digits.pips = 0; }
       // OrderSend(... Slippage.Pips * pips2points, Bid - StopLossPips * pips2dbl
