kiraan yg betul2 tepat saya lama suda ndak kira2 (spread ndak dikira sama).. so ini ialah pendekatan untuk gitau mcm mana margin call tu bole terjadi...
( XXXUSD punya pair punya kiraan)
hemm... definisi simple margin call maksudnya, broker ndak kasi benar
account kita -ve balance.. so dia tutup account kita before -ve..
==================================
Matematik dia
c = capital size or account size
p = pip price
n = pip number
c + pn > 0
n > -c/p ; ubah n sebagai yang ingin dicari
================
i) harga pip $1, account $1000
ii) harga pip $2, account $1000
iii) harga pip $3, account $1000
iv) harga pip $4, account $1000
i)
c = $1000
p = $1
n > -$1000/$1
n > -1000 pip
domain n = {-999,-998,-997,...}
# sekitar -999 pip ke atas2 sikit kana tutup suda tu akaun or Margin call
ii)
c = $1000
p = $2
n > -$1000/$2
n > -500 pip
domain n = {-499,-498,-497,...}
# sekitar -499 pip ke atas2 sikit kana tutup suda tu akaun or Margin call
iii)
c = $1000
p = $3
n > -$1000/$3
n > -333 pip
domain n = {-332,-331,-330,...}
# sekitar -332 pip ke atas2 sikit kana tutup suda tu akaun or Margin call
iv)
c = $1000
p = $4
n > -$1000/$4
n > -250 pip
domain n = {-249,-248,-247,...}
# sekitar -249 pip ke atas2 sikit kana tutup suda tu akaun or Margin call
Set_Pasangan_HargaPpip_PipMarginCall = {($1/pip, >-1000pip ), ($2/pip,>-500pip), ($3/pip,>-333pip),($4/pip,>-250pip),..}
==============
Kesimpulan...
kalo kita ndak pasang stop lost... maksud dia "stop lost" = "margin call"
semakin besar harga per pip, semakin cepat margin call
