So it's kind of disappointing to say this went exactly according to plan, because it's not as good for teaching about the process that way, but it's the truth. I will let you in on a few secrets and things you can learn from it though. And I'm not taking total credit for things working out perfectly, by the way. Sometimes things just happen right in the market and this was one of those times. I will take credit for the fact that I put myself in a position to reap the benefits, though, and there's a lesson in that for everyone.
I didn't choose ABNB by accident for this trade. There were multiple stocks that my system flagged as short candidates. I chose ABNB because after backtesting it, I thought it gave me the best chance to be successful. That's a lesson on its own that is good to be reminded of. I don't care how you trade, whether it's chart patterns, fib levels, trend lines, technicals, whatever. There will always be multiple stocks that fit the parameters of your trade. Simply choosing the first one you come across is not putting yourself in the best position to win the trade. One of those stocks has an 'edge' over the others, and it's up to you to find it if you want to be as successful as possible when trading. The more finite your trading capital is, the more important that edge becomes, because you can't afford to be wrong as often when your capital is limited.
I chose ABNB because in my backetest, 61 of the 65 signals were profitable in 20 days or less. 75% of the signals resulted in wins in 3 days or less, and 50% of those trades were profitable in ONE trading day. Those stats were better than any other stock I was considering. That doesn't mean the trade HAD to work out the way it did, but I gave myself the best chance for it to do so, and sometimes that's the difference between a winning trade and a losing one.
In the backtest, the median gain on all trades (including some big losers) was .98%. So I wasn't holding the put, waiting for an 8 or 10% drop in the stock that some of the signals had produced on ABNB in the past. I was looking for a profit. Period. That's lesson #2 - DON'T BE GREEDY.
I have lost a lot of money trading while waiting for a win to get bigger or an already big win to get huge. I know that every new day in the market brings with it the unexpected. I think there's a decent chance ABNB goes down even more tomorrow, and if it does, a big drop would not surprise me in the least. That would make me more money, obviously. But a big run up might happen too, and that's why this was always designed as a 1 day trade.
Many of those wins in my backtest would have become losers holding them longer than it took for them to become profitable, especially the 1 day wins. I play the odds, and the odds said to walk away with a not quite 11% gain in one day. There was a 100% chance I'd have more money than I started with if I did that, and an almost 50% chance of losing that profit and then some staying in the trade 1 more day.
As for the put option itself, this was the biggest unknown for me. With stats like the ones I just described, it was hard not to do a weekly option instead of 2 months out. When 75% of your trades would close in 3 days, it seems like the way to play it. And long term, it might be. But 65 trades isn't a huge sample size, and my short system still is in the training wheels stage. I knew I'd make more money with a weekly, but if the trade went longer than a couple of days, even if the stock dropped, time decay might have cost me my profits.
Is it hard knowing I could have made 52.2% today on this trade instead of just 10.9%? You bet it is. But when I'm trying something new, I err on the side of safety. This is a long game I'm playing. I want to have as much money left available to trade as possible once I get to a point where I'm super confident that what I'm doing is going to work, and I was nowhere near that level of confidence going into the trade. The longer option gave me more time for the trade to play out, had I needed that. I also really didn't know what, if any, affect volatility changes were going to have. I had an idea, but I don't trade options enough any more to have a good handle on that, so I used the longer option as a way to minimize any changes in vol, while I was in the early stages of testing this system.
Looking at it now, the smart play on future trades involving ABNB might be to use a 1 month or even 2 week option and simply close the trade within 5 days, win or lose. I don't know that yet, and it's going to be a while before I do. So for now, I'm happy with how the trade went, but I feel like I'm still a long way from knowing the best way to take advantage of the variables and optimize profitability. But every trade, I'll learn something that gets me closer to that goal. In retrospect, maybe leaving some money on the table was a good learning experience. There's something to be learned from every single trade I take, win or lose. Being committed to doing that learning every day with every trade has made me a MUCH better trader and it will help you too, if you take the time to do it.
