Given the recent conditions we have all seen that certain industries prevail in difficult times.
Companies focused on agricultural endeavors will always be needed as the stable production of food
is the basis on which our society survives.

As a robotics & sensor engineer working with all types of farmers in the Western Cape, I am well
aware of the current technological developments in the agricultural industry. Recently the farmers that
I have spoken to are more open to new technologies, as they are in need of practical solutions to complex
integrated technological problems on their farms for which the local market only provides partial and over priced solutions.

Having identified these problems over the past few years and also growing up as the son of a farmer I have
a special insight into the most practical and cost effective solutions for over 30 major problems integrated into one platform consisting
of several integrated hardware and software solutions ranging from custom sensors to interactive databases & data visualization tools.
My brother and I are working together on this platform in our private capacity and we are busy starting a company together.

Our aim is to retain a certain portion of control, however we want to put the power of local development in the hands of the farmers.
The model which we have been considering consists of acquiring venture capital by selling shares to prospective buyers which include a profit share,
first & discounted access to new technology and a large growth on the initial investment. Ideally shareholders would be able to help provide
aid or advice in their own field of expertise in order to help the company grow in the right direction

I am posting this in this community because I have followed it for a few years now and back in my student days I planned on going in a financial direction, however any business sense that I used to have has washed away over the past few years as I have spent all my efforts growing and bettering myself in an engineering direction.

If you have any suggestions or recommendations for me regarding my business prospects it would be much appreciated.
Also it would be interesting to get some opinions on the topic of agricultural investments & recent developments.

Whenever the quantity of a share reaches 0 (zero), the avg_cost variable for that specific share should be zeroed,
(avg_cost = 0.0;) so that when ALL shares are sold (qty = 0) and more are bought later, the avg_cost of the shares sold a month ago doesn't affect the average cost displayed of the new shares you are buying.

Each transaction of a specific share should contribute its weight to the avg cost, so if 50 are bought at R1 then 100 bought at R2 and 40 sold at R3: (the avg cost is R1*(50/150) + R2*(100/150) = R1.67)
Now when the 40 shares are sold, the total qty of shares are reduced, but the avg cost should remain unchanged because selling price doesn't affect the buying price, so now we have 110 shares bought at R1.67 each, and when we buy again, say 90 at R2.50, then avg cost = (R1.67*(110/200) + R2.5*(90/200)) = R2.04.
The transaction fees and tax on share profit can be calculated seperately as I beleive you are allready doing.
