It would be nice to know how much I have in pending transactions, both for afterhours trading, as well as dealing with the 20 minute delay (though to a lesser point)
example 1:
I have 1000 e$
I go to buy XYZ at 2.00 a share, the computer tells me I have enough to buy 450 shares (and still have 100 left)
I choose to only buy 200 shares. (400.00, leaving 600 e$)
I then go to buy ABC at 3.00 a share. The computer still calculates off of the 1000, not the 600, so it states that I can buy 300 shares, even though I can really only buy 166.
Example 2:
I have 1000 e$.
I go to buy XYZ at the same 2.00 a share, can buy 450, etc.
I buy all 450.
I post some messages, mange to gain another 1000 e$ (at this point I have 2000 as the first trade has not gone through yet)
I go to buy ABC at the 3.00, and the computer states I can buy 633 shares, not the 333 I would be able to buy in truth.
Example 3:
I have 1000 e$
I buy 200 shares of XYZ (leaving 600 e$)
I sell my 333 shares of ABC (giving me 999 less commission)
At this point I still have 1000 as none of the trades have happened yet. If I go to buy DEF at 5.00 a share, the computer will say I can buy 180 shares, when in truth I can buy closer to 300 shares and be okay.
Possible solution:
show the expected money in and out, and you can build a 10% fudge factor into it even. that would leave you with something like this:
Example 1:
(I just bought the XYZ and am going to buy the ABC)
Your total e$ : 1000
pending sales: 0
pending buys: 200 @ 2.00 = 400 (figure 440)
amount to spend (10% fudge factor): 560
You could buy 153 shares and still have 100 e$ left.
Example 2:
(ready to buy ABC)
Your total e$ : 2000
pending sales: 0
pending buys: 450 @ 2.00 = 900 (figure 990)
amount to spend (10% fudge factor): 1010
You could buy 303 shares and still have 100 e$ left.
Example 3:
(Again, ready to buy the last stock)
Your total e$ : 1000
pending sales: 333@ 3.00 = 999 (figure 899)
pending buys: 200 @ 2.00 = 400 (figure 440)
amount to spend (10% fudge factor): 1459
You could buy 271 shares and still have 100 e$ left.
I realize it isn't perfect, but in reality, if a stock moves more than the 10% in the 20 minutes, or more than that in overnight trade, it could still over extend you a little bit, but at least it would be close almost all the time.
This could even be extended a bit to allow you to specify the % fudge factor to use in your profile for if you wanted to cut it closer, or if you tend to pick high, fast movers and want to allow a bit more leeway.

This is actually in the works, or was some time back. The idea is that when you enter an order your funds are encumbered so that you cannot "over buy" which would result in orders being cancelled. The same thing would happen on the sell side with your stocks. You would not be able to enter more than one sell order for the same holding.
No expected release date, but this is in the plans. |
