This procedure runs when the following occurs in any of the trader's accounts: balance change, group account changes, default amount change, markups adjustment.
The procedure OnAccountChange has two parameters:
| 1) | Action: TDataModificationType – the type of change: |
a) dmtUpdate - balance change, group account changes, default amount change, markups adjustment
| 2) | Account: TAccount – the object from the TAccount class that was affected by the change. |
The objects Action and Account can be accessed within the procedure.
Example:
Let us write a strategy that will output all the changes that take place in the Account Information Window into the log.
The script will be as follows:
Const StrategyName='My Strategy';
procedure OnAccountChange(const Action: TDataModificationType; const Account: TAccount); begin Log('Some Changes were made in accounts table.'); Log('Action: ' + IntToStr(Action)); Log('Account: ' + Account.Id); Log('Balance: ' + FloatToStr(Account.Balance)); Log('Equity: ' + FloatToStr(Account.Equity)); end; |
As a result, the procedure OnAccountChange will run every time any change occurs in the Account Information Window, and the information about the changed account will appear in the log.
As a result, the output may look something like this:
