True Bid/Ask spreads on 3xETF, 9+ months out, out-of-the money calls

Most people like to sell premium and collect money.  Me, I like to buy premium in anticipation of a melt-up.

Today I placed an order to buy TQQQ 76.67C, Jan 2019, and another order to sell the same call option. I did this to see what the true market bid/ask spreads are.

In the morning, Schwab was publishing bid@1.40, midpoint@2.60 and ask at 3.80.   There had been no volume on this contract for several days, and the market has been up over the last few days/weeks.

I started placing orders to buy at $1.40, going up in 20c increments until the bid dropped again when I removed my order. The marketmaker bids rose and stayed elevated to $2.50, at which point my bid became best when my order was in, and the bid dropped to $2.50 when I removed my order.  I got filled at $3.50. I bought 10 contracts.

Then I sold  1 contract. Started at $3.50, got filled at $3.30.

So the real spread was $3.30-$3.50 (about 6%), and not the $1.40-$3.80 (46%)  that the platform said at the beginning of the day.

 

Compare to QQQ options for the same date (Jan 2019) — the same % out of the money (7% for QQQ, 21% for TQQQ) is 190 strike. Before starting, bid is $3.28 to ask of $3.35  (2%) . Using the same methodology buying 32 contracts and selling 2 I got filled buying at $3.29 and selling at $3.28 (0.3%).

Above is the view before starting QQQ trade

Above is the view after completing both QQQ trades (buying and selling).  Notice I am all of the volume. Started at 405, I bought 32 and sold 2, ending volume is 439.

 

So, the final analysis is as following:
