The boxes around the levels represent entry/exit zones where anything is suitable if the levels themselves arent used.
Two trade setups within, shorter term and slighter longer timeframe.
The yellow box/levels signify a short term trade entry range. The orange dotted line represents the stoploss to any entry in this yellow range. Entry in the yellow zone should target the purple zone/levels.
The green box/levels signify a slightly longer term trade entry. If price moves below the yellow zone this would be the entry targets. With a red dotted line representing the stop loss relative to these entries. The targets for entry in the green zone are the teal zone above for a longer playing trade. Although entry in the green zone could also take profits at the purple zone as well for a shorter/safer exit in profit.
Entry in the yellow zone could also use the red dotted line as a stoploss if you can swing a riskier stop loss on entry.
