SP500 entering sell zone. 1:3 R:R sell trade

Last week I said that SP500 is drawing a nasty picture and although we can have a rebound from the recent ascending trend line, this will not change the longer-term bearish perspective.
Indeed, we had this rebound and now the SP500 index is trading in a very strong sell zone that is set between 4100 and 4200.
In my opinion, a reversal to the downside will follow from this zone and traders should look for selling opportunities.
This outlook is intact as long as the price is under 4300 and bears can target the previous low for their sell short trades.
