Most likely, your exploration is using an indicator that performs an exponential calculation (ex. RSI, ADX, exponential moving average, MACD, etc). Such indicators will have a different value depending on the amount of data they are calculated on. Make sure that you load the same amount of data on your charts as the amount in your exploration options. To check the load option: For the chart, click on File | Open Click on Options | Load options. For the exploration, click on Tools | The Explorer and click on options.
