近日学习买卖奥谱神,基本是bought at ask price and sold at bid price, 有一个问
题: all I could see are the bid and ask price, however, I just found that
someone could set the bid or ask price in between but I could not see it.
Can you show me how could I do it?
In fidelity, I have the following order choices:
1. Market
2. Limit
3. Stop loss
4. Stop limit
5. Trailing stop loss ($)
6. Trailing stop limit ($)
I only understand and used the first two choice, googled the rest but still
not clear..., anyone can help to explain how to hide my bid or ask price?
有包子酬谢!
A lucky story: Before I went to work yesterday, I set a limit sell of 20
calls at 1.5 (bought at 0.7 two weeks ago), and set a fishing price of 2.12
for a stock I already had (tried to add 5k more). When I checked them at
lunch, I found both filled--I scored 1k at the lowest price of the day for
the stock (lucky me), but....the number of my calls turned to be 40!!! I
tried to sell my 20 but I got another 20 at the highest price yesterday!!!
Well, I had to hold it since the price went done to around 1.2 then......
BUT today, it had been traded as high as 1.80!!!!
I did not catch the high but sold all 40 calls at 1.7---extra 30c for 40
calls in one day!!!!
I don't know what to say, I am still learning and does not even know the
basics such as the question I had above, and making mistakes when 下单....
but I could still making money!!!! What a market, what a amateur's luck!!!
Good luck to everyone!!!

可以使用兩個鏡頭，在同一個光軸上。一個視場寬廣，一個長焦視場狹窄。使用寬
廣視場搜索飛鳥。相機可安裝在自動伺服架上。在寬廣視場中一旦看見目標，手指
一點，搖架自動轉向對準飛鳥。
不知道寬廣視場相機可否測算出飛鳥距離，如果可以，距離信息可以傳輸給長焦鏡頭
做預對焦使用。
跟踪是個問題，似乎使用手指指點或者用筆在大的控制台上跟踪飛鳥是個辦法。應該
比遊戲裡面打飛機容易。指點設備跟著飛鳥，鏡頭隨動。一旦對焦，開始拍攝。
控制台可以是作為RV套件，拖在車後面。豪華的可以坐多人。簡單的就一個人。相
機公司因此多一個發財的生意。以後打鳥的人擔心的就不是對焦問題，而是如何把五
百磅的控制台移到攝影地點。
這樣諸位大師以為可行嗎？

这里有问题。
即使你把买卖搞错了，他们也不能把最高的价格给你的。
比如我就经常买卖不分的，但是如果当是的市价是1.3，你说买进1.5，他们也应该给你
1.3买入才对的。

也许是因为你买的options，每天的交易量几乎没有，10-100个合同一天。

你第一步搞错了。
选sell to close，但你选了buy to open

今天卖时,bid价1.65, ask price 1.85, I tried 1.8, then the ask price turned
to be 1.8, I don't think anyone would pay ask price at 1.8 to buy my calls,
so I tried 1.75, again, it clearly show the ask price of 1.75, the same
problem to sell my calls, so I almost try to use the market price of 1.65 to
sell, then I thought I might try 1.7, and it filled...so it confirmed that
someone could set a bid price of 1.7 that I could not see!!!!
I got to know how to do this, anyone can help? thanks!!!

然后你又选了一个追涨的，
Trailing Stop Limit Orders，依据就是ask价格。

这1.8就是你的ask价格，因为你的ask价格最低所以被显示出来了。

Oh, that is possible, since I always open two windows, one for trading, the
other to check the option chain for number of availability at those bid and
ask price, I always click buy to open to check the numbers, maybe I did it
directly from checking window......
I have paid almost 400 commission fee in the past two weeks, I hate
partially filled so I check all the time, but I realized that there are
hiding orders....the day before yesterday, I checked and bought all the
available 35 calls at one price, then I found the ask price still the same,
I checked again, found more there, if buy again, have to double pay the fee.
...frustrating....

At least twice I got the calls at the price below the ask price right away,
which made me think the lowest ask price might not always show up...but each
time I enter a lower than ask price, it shows up all the time, which made
my calls/puts hard to be bought at above bid price......
It has been a fun learning process...

信息不对称。
你看到的是部分信息，中间有市场Quote，也有可能MM的自动交易策略，根据bid-ask
而改变跟进。

Even though I could not figure out the info. behind your words, 信息不对称你
看到的是部分信息--is that due to the market? or due to my broker who covered
some of the info.?
I did have one such experience with TD, once I tried to short a stock, but
TD did not let me do it, and the next day, that stock went up big...that was
the first time I have changed my opinion on TD ,assuming they were trying
to protect my assets....maybe not, I don't know.
Also I have encountered a couple of times that I try to buy stock by
entering the ask price, once I click, it did not execute, but when I reload
the page, I found the price went up, then I entered the new ask price, the
price went up again.....I had never thought deep on such events, just too
deep in the market, lots of unknown....
Thanks for your info.

一般来说，选择bid ask中间或中间偏上的limit order都会成功，例如bid 5.00, ask
5.40,你设5.20成功率70%以上，5.30基本马上filled，但是请注意前提是波动没有很剧
烈的期权才可以。对于波动大的股票，像tsla，你很难抓住最优买入价的，一般都是看
time value +（股价—strike price）给自己一个目标价位。其实你量不大的话不差那
三五十块钱。
另外，好像是3块还是多少钱以下的期权，可以5分钱increment,3块以上的是1毛钱
increment
