Added fast charting option (Online). The function performs charting without waiting for a bar closing. In other words, the current Bid/Ask price is used as a charting basis.
The initial charting is performed using history data (OHLC prices), while the further ones are performed depending on the price changes. The system of protection against incorrectly specified parameters has been improved.
Thus, the following parameters have been added:
- Type building - charting type:
1. Typical (one minute) - the same charting as in the previous version
2. Online (fast) - real-time charting based on Bid/Ask price
- Price for Online type building - price type for real-time charting:
1. Bid - Bid price
2. Ask - Ask price
- Protection on instability - protection against unstable work:
1. No (errors may occur) - no protection, errors are possible due to incorrect data
2. Yes (normal protection) - medium protection (there is a possibility of charting starting not from an initial date)
3. Yes (enhanced protection) - enhanced protection (chart end is displayed)
The following parameters are ignored after preliminary charting in Online mode:
- Period of the analyzed data
- Update period chart
- Type price for building
The following parameter is ignored in Typical mode:
- Price for Online type building
Attention! Remember the following while testing:
- 'Start date analysis' parameter should have a date that is earlier than the test start in the strategy tester.
- 'Step' parameter affects the charting rate and may cause an error if its value is small, while the initial date ('Start date analysis' parameter) is very early.
- 'Start date analysis' parameter affects the charting rate and may cause an error if its value is set to a very early date, while the step ('Step' parameter) is too small. This parameter also affects downloading history from the server and may suspend initial indicator operation notifying of that event by the error message (Copy error).
