Scope of work: I am seeking a financially literate (derivatives trading, Black-Scholes, option greeks, binomial models) programmer. Phase 1 will be to create a simple random walk Monte Carlo (or geometric brownian motion) simulating the price of a stock with the volatility as a variable that dictates how much percentage the price can move from time1 to time2, following a log-normal distribution. Simple enough since I created a rudimentary model in google documents that does just that. The more complex part is to design a trade strategy that is based on a modified martingale which will go long/short. I have several google docs available that go into the mechanics of the strategy. Phase 2 will implement the same strategy (should it prove profitable) using theoretical options pricing models to achieve the same results as phase 1 utilizing call/put verticals and condors. Phase 3 will be a backtest of the strategy on real data.

Program will chart 10 years of data from a specified date (variable). Running program will chart 10 trading days before variable date and 60-90 days after variable date. Each years chart will on the same screen, one on top of another. An average of all ten years will need to be highlighted to be distinguishable from all other charts. To choose a common integer for each yearly (60-90 day time frame) chart, The high of the time frame should be given the value of 99. The low of the time frame will be given a value of 1. All other number will fall into place accordingly. This way the $$price will be converted to a variable rather than dollar figure. Any questions please feel free to contact me. I will want to see a working sample before contract is awarded. This job will lead into maintaining...

Hello, I have an application which bin-packs svg objects into specified size bins. I would like to make some enhancements to the algorithm and functionality. 1. Make sure all processed jobs are running ~10 seconds no more than 20 seconds. 2. Pack objects more efficiently. 3. Work with someone to find best ways to optimize space use and brainstorm other use cases. What this applications purpose is to place images on paper which are then printed. Each sheet which is specified will be sent to so a customer. Obviously I want to save as much space as possible as that impacts the bottom line. Reducing whitespace is how I waste less money in material costs. Some of the enhancements I have been brainstorming have been focused around packing the irregular shapes in to sub-rectangular shapes which would then be packed in to a larger rectangle. I will need to provide some examples for sure. I would like to also automatically label these sub-rectangles so I know which order they...
