1. That is also why you do NOT use TickValue by itself.
2. That is also why you must normalize PRICE for pending orders.
   

double DeltaValuePerLot(string pair=""){
   if(pair == "") pair = Symbol();
   //{Value in account currency of a Point of Symbol.
   // In tester I had a sale: open=1.35883 close=1.35736 (0.0147)
   // gain$=97.32/6.62 lots/147 points=$0.10/point    or $1.00/pip.
   // IBFX demo/mini       EURUSD TICKVALUE=0.1 MAXLOT=50 LOTSIZE=10,000
   // IBFX demo/standard   EURUSD TICKVALUE=1.0 MAXLOT=50 LOTSIZE=100,000
   //                      $1.00/point    or $10.0/pip.

   // https://www.mql5.com/en/forum/127584 CB: MODE_TICKSIZE will usually return the same
   // value as MODE_POINT (or Point for the current symbol), however, an example
   // of where to use MODE_TICKSIZE would be as part of a ratio with
   // MODE_TICKVALUE when performing money management calculations which need to
   // take account of the pair and the account currency. The reason I use this
   // ratio is that although TV and TS may constantly be returned as something
   // like 7.00 and 0.0001 respectively, I've seen this (intermittently) change
   // to 14.00 and 0.0002 respectively (just example tick values to illustrate).

Ah, now I know! Thanks :D 

obviously he was wrong, he wrote that "this is a 4-digit broker where the spread is 2 pips or 20 points ". Why are you arguing about that ? On a 4-digit broker 2 pips is 2 points and not 20 points. Point.

A pip is a pip but a point isn't a point, on a 4-digit broker a point is 0.0001, on a 5-digit broker a point is 0.00001. If it "doesn't matter whether the broker is 4 digits or 5 digits" then what you wrote is a non sense : 1 point=10 point is absurd.

Ahh, I tried to some summarising to finally clear things up but I can't get the wording right and still be simple and understandable! haha, why is it so hard?
