loadStatus

saveStatus(string FileName)

loadStatus(string FileName)

Saves and loads the current trading status to a .trd file in the Data folder. The file contains the status of open real and phantom trades, the status of the sliders, and component specific variables (AlgoVar). This function can be used to resume trading at the last stored state in case of a server crash or reboot, or to let a fallback server take over the trading in case of a hardware failure.

Parameters:

FileName

Name and path of the file, or 0 for a default name like "Data\\scriptname.trd".

SaveMode

This variable determines by several flags what's saved or loaded in the .trd file in [Trade] mode or when calling the saveStatus/loadStatus functions.

Flags:

SV_SLIDERS - save/load slider positions (default).
SV_ALGOVARS - save/load all AlgoVars (default).
SV_ALGOVARS2 - save/load all AlgoVars2.
SV_TRADES - save/load all open trades (default).
SV_STATS - save/load statistics data, to be continued in the next session.
SV_BACKUP - after loading, save a backup of the .trd file (default).
SV_HTML - after loading trades in [Test] mode, generate a HTML file with the list of open trades.

Type:

int

Remarks:

Depending on SaveMode, the system status is automatically loaded in [Trade] mode at session start from a Data\*.trd file.The file is updated at any trade or at the end of a trading session. Set SaveMode = 0 for preventing the automatic saving and loading. In [Test] mode the saveStatus/loadStatus functions can be used for saving or loading.
The flags can be combined by adding (see example), and can be separately set or reset with the setf and resf macros.
For properly resuming statistics from the previous session, the end of that session must be within the LookBack period of the current session.
All needed assets and algos must have been selected in the initial run for loading their AlgoVars; slider ranges must have been set in the initial run for loading slider positions. Static variables that have an effect on trade handling must be restored with putvar / getvar.
Trades can be alternatively loaded directly from the broker account with the brokerTrades function. In that case make sure that the SV_TRADES flag is not set. The broker API must support the GET_TRADES command.

Example:

function run()
{
  if(Bar >= 1) { // default asset is selected after first run
    AlgoVar[0] = 123;
    SaveMode = SV_ALGOVARS+SV_ALGOVARS2; 
    saveStatus("Data\\Test.trd");
    AlgoVar[0] = 456;
    printf("\n %.0f",AlgoVar[0]);
    loadStatus("Data\\Test.trd");
    printf("\n %.0f",AlgoVar[0]);
    quit("ok!");
  }
}
