This is rare, SPY is currently near the 200 week moving average. The 200 week moving average for SPY and QQQ has been a very reliable indicator since 2011. Similar to my other idea I posted regarding NQ/QQQ, it is possible that SPY could bottom around this area. If not, we could see a sharp drop through it as many institutions buy the 200 week MA and may close their long positions if it doesn't hold.
My goal is to find the best risk:reward setups. For instance, if you risk $1,000 at a chance to make $5,000, you can afford to be wrong 4 out of 5 times and still not lose money. I hit my targets over 50% of the time.
