Overview.

The PonTan chart shows price movements over a five-day period, including the day recorded in the logbook. Only the 15-minute chart is displayed. The mouse wheel can be used to zoom in and out, and left and right scrolling allows you to go back and check past price movements. The vertical line indicates the date line and is always visible, but the date at the bottom may be omitted depending on the zoom factor. Charts for the day of the logbook are automatically updated every 15 minutes. When the date changes, only the chart corresponding to that day's logbook is subject to subsequent updates, while charts for other dates are fixed. This is intended to "keep a history of the charts you were looking at in real time that day".
The four currency pairs that can be displayed are.
- USDJPYUS dollar/Japanese yen
- EURUSDEuro/US dollar
- GBPUSDBritish pounds sterling/US dollar
- AUDUSDAustralian dollar/US dollar
PonTan trades essentially only in the straight dollar.
This is due to the fact that technical analysis is more effective than in cross-currencies, making it easier to make clear trade decisions.
