will this years history repeat itself?

When I look at the market for this year I start to see a trend. The biggest sell offs are usually on the last month of each Quarter. March, June, and September. Will this trend continue for this month? It is still a bit early to say but if this trend remains consistent we will see a massive sell-off by next week as early as tuesday or wednesday.

We also see that the volume is beginning to weaken. However, This can also indicate a consolidation and preparation for a massive push up before a sell off. regardless in my opinion we are heading for a big correction. Spy is near the top and I am starting to see a triple top on spy. I will be placing a few short positions right now but in case i entered to early I will be cutting losses around 375 and analyze further to time a better set up to short. usually I am not bearish but this market is just super ridiculous and way over hyped with the news. This is not advice only what I see and what I plan to do. I am entering put contracts expiring next year. If the market will get corrected it will either be this month or as early as next month January.
