ROKU Trade on May 9, 2019 09:43 from kerobo0000: Tradervue User Stock Trades.

Rationale:
-ROKU reported better than expected earnings
-name has been known to move after earnings/be real sensitive to catalyst
-high SI (9.5%)
-$71 was a key resistance level from 8/2018; price gapped right up to this level immediately after the announcement
-ATH was at $77.40 and this was the next resistance level

Recap:
-on the open, ROKU traded down to $69 then blew right thru the $71 level in the first 5 min bar
-during the 3rd 5 min bar, I noticed there was some consolidation around the $74 level (on 1 min chart there are two red bars around this time)
-began seeing the large lots going off around this level (large lots at the bid were followed by price moving higher), and price couldn't make it below 73.90 and continued to trade higher every time price tried to push lower
-entered into a 10 lot around the $74 level
-couldn't reduce risk on this trade (buy selling further OTM calls) & swing this position for a few days as I didn't have any day trades left
-one thing I noticed while I was holding was when ROKU was close to breaking a level, the spread on the 75C really widened as if the market makers are expecting the move and trying to protect themselves (selling to buyers at a higher price and buying from sellers at a lower price)

How much risk should/did I take?
I took $3,230 of risk (total position size); this was not big enough given the catalyst & SI - however in real-time, the only thing that would've given me conviction to get bigger is if the overall market was also positive today (market traded higher in the afternoon but still closed down 0.3-0.5%
-note: it took 3 separate executions to get filled on the 10 lot (didn't think it would get filled b/c price kept moving away from limit order); something to keep in mind as I may have to incorporate stock and different strikes to get bigger on stocks that have spreads wider than 10-15c (ROKU spread was 25-40c)

things to improve on:
-staying laser-focused on the tape and realizing heavy buying in real-time; i was exiting the position without having a reason to exit
