Were tobacco warehouse receipts an economic form of money during part of the Colonial period in Virginia?

Modern trading systems are mechanic, run automatically on computers inside trading platforms and decide their position against the market through optimized parameters and algorithmic strategies. These systems now, in most cases, comprise high frequency traders, especially in the Forex market.
In this research, a piece of software of an automatic high frequency trading system was developed, based on the technical indicator PIVOT (price level breakthrough). The system made transactions on hourly closing prices with weekly parameters optimization period, using the d-Backtest PS method.
Through the search and checking of the results, two findings for optimization of trading strategy were found. These findings with the order they were examined and are presented in this paper are as follows: (1) the simultaneous use of “long and short” positions, with different parameters in a hedging account, acts as a hedging strategy, minimizing losses, in relation to a “long or short” in a non-hedging account for the same time period and (2) there is weak correlation of past backtesting periods between the same systems, if they are configured for “long and short” trades, or for just “long” or for just “short”.

Smoking, as one of the main causes, is a negative factor associated with many diseases. The primary objective of the research is to determine the effect of innovation on selected smoking indicators in a sample of countries of the Organization for Economic Co-operation and Development (OECD). Four variables enter the analytical processing, such as Global Innovation Index, Population ratio of daily smokers (age 15+), Daily smokers (age 15-24), and Tobacco consumption in grams per capita (age 15+). These variables were included in the research from 2011 to 2018. The simple linear regression – the Ordinary Least Squares (OLS) model – and correlation analysis – Spearman’s rank correlation – was used for statistical processing. The results show that the effect of innovation on the ratio of daily smokers over the age of 15 to the total population may be considered a highly significant relationship. The effect on the annual tobacco consumption per capita is the second most significant relationship, and the effect on the ratio of daily smokers over 15 and under 24 years to the total population is the least significant compared to the previous two cases. Correlation analysis shows similar outputs. All these relationships may be considered negative. It is possible to talk about the lost innovation potential associated with smoking, primarily in the productive part of the population. A higher level of smoking can be associated with a lower level of innovation. Also, innovation negatively affects the tendency to smoke. Therefore, public policies should promote a healthy lifestyle.

This examines the special use of art works as a store of value in Germany during the Third Reich era. Some Jews were able to buy their freedom, as the fascists closed in. Then as the Third Reich fell, some escaping fascists used art works to secure freedom outside of Germany. One of the characteristics of money is a store of value. When confidence in a currency is present, the more conventional form of money takes precedence. A respected, economic form of currency and coin has all three elements of money: medium of exchange, store of value and unit of account. This last trait is especially absent when using various art works as money, as there is no agreed upon unit of account with such different art. Furthermore, art works could not qualify as a medium of exchange, since only a very small amount of the population was involved in this way of dealing in art during the stressed times for the Third Reich.
