Improve the widget related to the Economic Indexers

[CarlosOliveira1988]

Is your feature request related to a problem? Please describe. Sometimes, we wish to compare our investment contributions against some Economic Indexers such as IPCA, SELIC, etc. This usually help us to check our performance (look to the past). Also, it is useful to improve our decisions to the future.

Describe the solution you'd like Improve the set of tabs with buttons and any other GUI component to make possible to set parameters such as initial/final dates, initial values, etc.

Describe alternatives you've considered Inputs:

• Initial Value

  Default: R$1000,00 A single 'QLineEdit'

• Initial Period:

  Default: the initial period of the data series A pair of 'QComboBox'

• Final Period:

  Default: the final period of the data series A pair of 'QComboBox'

• Aditional Interest Rate:

  Default: 0,00% A single 'QLineEdit' and a single 'QComboBox' Special conditions:

  • If 'IPCA' or 'SELIC': the total rate by default is 'table_rate + additional_rate' [PRE FIXED]. Example: 5.54%.
  • If 'CDI': the total rate by default is 'table_rate * additional_rate' [POST FIXED]. Example: 130.00%.
  • If 'FGTS' or 'NovaPoupanca' or 'AntigaPoupanca': the total rate comes from the 'table_rate' [NONE].

Outputs ('QLabels'):

• Final Gross Interest Rate/Value
• Final Net Interest Rate/Value, taking in account:

  • IR: 15.0%
  • IR: 17.5%
  • IR: 20.0%
  • IR: 22.5%

Actions:

• A button to start the calculation
• A button to plot the data graphs

HMI improvements:

• Include the 'Yearly' column in each tab, in order to display the 'yearly interest rates'
• Include an additional tab to set 'Inputs' that will be crossed with all economic indexer tabs, in order to compare results in different investment modalities
