Time frame analysis for short term and long term

Hello Guys,
when trading a 1 hour time frame, why does the auto close margin seem smaller, than when trading a 1min chart?

Always do a short time trade where there is a huge liquidity in the market. If you do so than you can save yourself from huge loss. Always do long term trade only on those areas where there is less liquidity or where you are fully confident about the success.
