US Stock Market: I have developed and tested a stock picking algorithms that identifies daily stock picks for investment (at any price point, industry, sector, etc.). Over the last 7 years, I have back-tested it 3 times on paper and I have actually made trades along the way to put money behind it in the real world. Each time and along the way, I continue to see a 95% success rate with my overall investment strategy. When I say success rate, I mean, I buy at the entry-point my algorithm dictates AND I sell at a predetermined percentage increase in the stock price for a gain at a predetermined price. The issue I have is that I have not been able to get a good methodology for estimating how long it will take for a particular stock’s price to increase to a certain point. No I don’t think it can be exact, but I should have an idea of what I think it would be close to; because it affects cash-flow. So the 5% non-success rate that I eluded to above is not really a “fail”; it just would be a situation of holding stocks longer than desired. So if you think about it from a cash-flow perspective, the number of shares, purchase price, and share price all play a part in the cash-flow; money tied up in a stock is money that can’t be invested in the new stocks that my algorithm produces. (For example, if I have 10k of cash to grow using my investment strategy, and 6k is tied up for 30 days before I can sell and get the gains; that could be 250 missed opportunities to invest that 6k in stocks that would have been bought and sold during that time frame.) I need an approach to rank the stocks that I would invest in on a daily basis, and it would be based on the belief that lower ranking ones would take longer to sell. This is what I’m looking for. Someone that wants to team-up with me and bring some value to this process. I can provide samples from my back-testing so you can see my buy and sell points. I also can provide historical stock prices for analysis, which would be the basis for some kind of statistical / analytical approach you would bring. There is no way to pay for this, because this would be too valuable. My stock picking is solid and proven, and your ranking system would make my stock picking much more valuable; because I can buy and sell at a more frequent rate and compound my investment money. I wouldn’t expect you to tell me your methodology; and I would not tell you mine. But you would have my daily pics and your ranking, which means you can do your own investing as well; we would share info to be successful. For the person that is willing to put in the time and can successfully developing a system that can be back-tested; it will be guaranteed success. This is really for the visionary, the thinker; the one that really sees themselves investing in the market. I run 7k stock tickers through my algorithm daily, so every day there is a list between 1 – 50 stocks that can be purchased. I don’t know if I will find one that is interested, but I thought I would give it a shot. If you are serious, open a message board. If you are looking for short-term money, get paid for your time, or to have any guarantees; this is not for you.

We need an algorithm that can handle the following use case. Let's suppose I have a set {​}​ and I compute the percentile rank. I want an algorithm that allows me to replace one or more values in the set (i.e. remove set member n5 and replace it with n9. Rather than re-compute the percentile rank across the whole set, I do the following: 1. compare the value the value replaced with the new value 2. based on some difference between the values adjust the percentile rank This can be defined in a statistical formula

Looking for a program to pre-build my pallets. I deliver bread and have to palatalize the product. The bread comes in 3 different sized trays. There are 15 different flavors of bread and that will fluctuate depending on the time of year. I have limitations on the height. I need them to all be close to level with one another so a tall pallet doesn't fall over on a short pallet during transportation. I need the flavors of bread to stay on the same pallet, doesn't matter which pallet the specific flavor is on, just that it is all on the same pallet. Right now I do this myself and pre-build the pallets for my dock workers so they know how to build. I have examples of what I do now that I can share with you.
