1. Column required: DATE, OPEN, HIGH, LOW, CLOSE, VOLUME.
   Volume is not required if you do not have the data.
2. Format of the date: DD/MM/YYYY or DD-MM-YYY. Example: Use 01-08-2018 instead of 1-Aug-2018.
3. Please do not leave any blank row/column in between.
4. Please do have sufficient data. Example: If you are going to backtest SMA (20),
   you need to have more than 20 data being uploaded. It is suggested to have at least 5-year period of data for a good quality backtesting result.
   10-year data would be highly recommended.

1. 必须有的栏/格式: DATE, OPEN, HIGH, LOW, CLOSE, VOLUME。
   如果您没有交易量(volume)，没关系。
2. 日期的格式: DD/MM/YYYY 或 DD-MM-YYY。例: 被接纳的日期格式为 01-08-2018。1-Aug-2018将不被接受。
3. 请不要在数据之间插入空行/空格。
4. 请确保您拥有足够的数据。例: 如果您想要回测SMA(20)，您须上载超过20个数据。若需要较好的回测结果，建议最少回测5年的数据。
   10年的数据回测会更佳。
