What is Pipsize?

  Problem solved.

  Actually, PRT seems to make a distinction between :

  – PipSize, which is the “point” as per contract specification

  – TickSize, which is the minimal increment in price.

  In the case of EUR/USD and BTC/USD with IG Markets, PipSize = 10 * TickSize.

  Hi,

  I am lost. How to calcuate then the size of your position with all these pipsize etc… ?

  For stock market, easy

  myPositionSize = ((myInitialCapital + STRATEGYPROFIT) *(myRisk/100))/(myStopFactor*myATR))

  But for the forex ? e.g. EUS/USD, what would be the formula of myPositionSize including these variables ?

  once myTickSize=0.00001
  once myPipSize=PIPSIZE
  once myPipValue= PIPVALUE
  once myLotSize=1000 (1000 ??? mentioned by default in probacktests)

  Thank you

  PIPSIZE should be used when you need to deal with both PRICE and PIPS in the same expression. It relieves you of having do do conversions yourself, as the system will take care of it.
  IF you want to exit at, say 20 pips less than current LOW, you will have to convert 20 (which is a numeric value) to a price, writing:

  SELL AT Low - 20*PipSize STOP //or LIMIT

  1	SELL AT Low - 20*PipSize STOP   //or LIMIT

  because writing:

  SELL AT Low - 20 STOP //or LIMIT

  1	SELL AT Low - 20 STOP   //or LIMIT

  would work for all instruments and assets with a price to pip ratio of 1:1, like indeces, but would fail for currencies (it would subract 20 from 1.01 on fx pair EurUsd).

  It should also be used with a division when you have to convert a price into pips:

  StopLossPIPS = (close - low) / PipSize //in EurUsd this will return 40, instead of 0.0040

  1	StopLossPIPS = (close - low) / PipSize  //in EurUsd this will return 40, instead of 0.0040

  This code works fine with DAX (Daily chart), without using PIPSIZE; you cannot trade the sime size of CONTRACTS as you do with SHARES, though:

  DefParam CumulateOrders = False ONCE P = 100 ONCE minLots = 1 ONCE myInitialCapital = 10000 ONCE myRisk = 5 ONCE myStopFactor = 1 //what is this ??? myATR = averagetruerange[14](close) myPositionSize = max(minLots,((myInitialCapital + STRATEGYPROFIT) *(myRisk/100))/(myStopFactor*myATR)) IF Not OnMarket THEN IF close CROSSES OVER average[P,0](close) THEN BUY myPositionSize CONTRACTS AT MARKET ELSIF close CROSSES UNDER average[P,0](close) THEN SELLSHORT myPositionSize CONTRACTS AT MARKET ENDIF ENDIF SET TARGET pPROFIT 500 SET STOP pLOSS 200 graph myPositionSize

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

  DefParam CumulateOrders = False ONCE P                = 100 ONCE minLots          = 1 ONCE myInitialCapital = 10000 ONCE myRisk           = 5 ONCE myStopFactor     = 1      //what is this ??? myATR           = averagetruerange[14](close) myPositionSize = max(minLots,((myInitialCapital + STRATEGYPROFIT) *(myRisk/100))/(myStopFactor*myATR)) IF Not OnMarket THEN    IF close CROSSES OVER average[P,0](close) THEN       BUY myPositionSize CONTRACTS AT MARKET    ELSIF close CROSSES UNDER average[P,0](close) THEN       SELLSHORT myPositionSize CONTRACTS AT MARKET    ENDIF ENDIF SET TARGET pPROFIT 500 SET STOP   pLOSS   200 graph myPositionSize

  Thanks a lot Roberto I think this is what I am looking for.

  So I assume  that for currencies, I would just need to add /PIPSIZE at the end to get the right position size.

  myPositionSize = max(minLots,((myInitialCapital + STRATEGYPROFIT) *(myRisk/100))/(myStopFactor*myATR)/PIPSIZE)

  Thank you Roberto.

   

  Could you please explain me what is this LotSize in yellow (see attached)? is that 1000 for EUR/USD ?

  Should not we consider that LotSize in the formula ?

  myPositionSize = max(minLots,( (myInitialCapital + STRATEGYPROFIT) *(myRisk/100))/(myStopFactor*myATR)/PIPSIZE/LotSize)

  or am I completely wrong ? 🙂

  I don’t know, as I never used it.

  It’s not requested by IG (for CFDs), it is requested by PRT (Futures), instead.

  I have no idea what’s it all about.

  OK Thank you Roberto

   

  BTW I have made some simulations, I think PIPSIZE should be placed here to get the right position size

  myPositionSize = PIPSIZE  * (myInitialCapital + STRATEGYPROFIT) *(myRisk/100)/(myStopFactor*myATR)

  Multiplying by PipSize is used to convert Pips into Price.

  I can’t spot any value expressed in pips in your code, though.

  If i take a risk of 50 eur

  With a stop at 5 pips

  The initial formula gives

  Positionsize = 50/0.0005 = 100 000

  If the. i do BUY 100 000 he will buy 100 000 K so 100 000 000.

  So i thought to come back to an “acceptable” position size i needed to divide multiply by pipsize which is 0.0001

  Is it a mistake ?

  Again :

  With a stop at 5 pips

  The initial formula gives

  Positionsize = 50/0.0005 = 100 000

  Then BUY 100 000 would buy 100 000 K so 100 000 000…

  So i thought to come back to an “acceptable” position size i needed to multiply by pipsize which is 0.0001

  Is it a mistake ?

  PipSize is NOT meant to make thing “acceptable” of “most favourable” or the like. It’s meant to convert Pips into Price and viceversa.

  Anyway, if your formula yields what you expect, then it must be ok!

  😀

  Sorry,  you know I am french and my English is…frenchy

  I meant “Consistent” instead of “acceptable” 😀

  i.e. the losses are indeed 50 Eur in backtests so consistent withe the risk I defined initially.

  I just hope this formula is then applicable to any forex pair.

  Thank you Roberto for all your support.
