VB6: Forex Margin Calculator
Creating a math prog that is trying to refine the value of the Lots text box.
Balance = 19.00
Leverage = 50
Lots = 1.0
If Balance = 19 then a for statement must decrease Lots until Lots x Leverage equals Balance. What is happening is for statement is decreasing Lots by 0.01 and Lot of 1.0 should reach .38 and change text box value to .38 and exit sub. What is happening is when lots equals .43 its saying .42999999999.

Is there something wrong with my code?


Dim Balance, Lots, Margin As Double
Dim Leverage As Integer
Const Mini = 50 '50.00
Const Standard = 100 '100.00

Private Sub cmdCalculate1_Click()
Dim i As Integer
'--- Memory ---
Lots = txtLots1.Text
Balance = txtBal1.Text
If optMini1.Value = True Then Leverage = 50
If optStandard1.Value = True Then Leverage = 100
'--- FindLots ---
If chkFindLots.Value = 1 Then
Dim Fbal As Integer: Fbal = Balance
For i = 1 To 100
If Lots * Leverage = Fbal Then
txtLots1.Text = Lots
Exit Sub
End If
Lots = Lots - 0.01
Next i
End If
'If Balance < Leverage Then 'Margins
' MsgBox "Leverage of $" & Leverage & ".00 is not met": Exit Sub
'Else
' Margins = Balance / Leverage: lblMargins.Caption = Margins
'End If
End Sub

Private Sub Form_Load()
'Reclaim memory
Lots = 0: ExtLots = 0: Leeway = 0: Balance = 0
'txtBal1 = "": txtLots1 = "": lblLeeway = "": lblMargins = ""
End Sub
