Default number of bars in chart when initially loaded

Hi thank you for reading my question .

When using in indicator with big periods ,e.g. [ema, close, 1000 periods]  the outcome is different when chart is initially loaded and after  i drag back more to the past .     I have realised that on my pc when a new instance of an indicator is created the default time frame is 1 hr and theres a default amount of bars too . Im wondering can i change the setting so when its loaded its default is 15 mins time frame and more bars be incldued . so I dont have to drag the chart to the right everytime manually when its loaded to include more past data .

Thank you very much
