The problem is when TSLA drops to 310 well before the

expiration date say mid September, but V shaped back up to be above 330 at the expiration. You missed the opportunity to accumulate even at 310. 

You could profit from the put spread when it drops to 310 for perhaps $12 by closing it at the time, but since you have a loss for the short leg put 310, you have to wait and cannot really buy it. By the time it reaches 330, you missed the accumulation at 310.  Basically you earned a premium of $12 in the process, but you still do not have the stocks. 

It is very hard to time the market. If you really want to accumulate, perhaps just wait for the price to drop to the price you want, say 310 here and buy it directly. 

My 2 cents in my experience of trading the ratio put spread in the past.
