"Double Seven, released by Trojan in late 1973, was the last album Lee 'Scratch' Perry would release on the label for some considerable time, and it was essentially the final album project he put together before establishing his own Black Ark studio. Opening track 'Kentucky Skank' sets the tone with a slow creeper whose frying sounds underscore its role as a praise song to the Colonel's KFC recipes; the cosmic Moog blips come courtesy of Ken Elliott at Camden's Chalk Farm studio, also prominently featured on U-Roy's double-tracked, stereo-panned gambling ode 'Double Six.' David Isaacs' 'Just Enough' was cut a few years prior, which makes it slightly out of phase with the rest of the set, though the enigmatic 'In The Iaah' sounds mightily fresh, with its uncredited chorus said to come courtesy of the Wailers. Perry's own 'Jungle Lion' has hilarious roars from the maestro at the start, strangely grafted atop a reggae re-make of Al Green's 'Love and Happiness.'
"Overall, Double Seven melds the soul, funk, reggae and dub elements that were constant in Perry's work during this phase. His enhanced audio spectrum and endless reference points would keep his music continually apart from that made by his peers."
Larry Connors and Cesar Alvarez revealed a trading strategy called Double Seven in their book Short Term Trading Strategies That Work. This is a fairly simple system that at the time worked very well among a wide range of ETFs. The book was published in 2010, and it would be interesting to look at the performance over the last decade since its publication.
In this article, we look at the performance of the Double Seven trading strategy over the last twenty-one years in a wide range of liquid ETFs. Does the Double 7 still work? Yes, the trading strategy still works, but Larry Connors has other strategies that work better.
The strategy has a few parameters and trading rules, including the close being above the 200-day moving average, the close being at a seven-day low for entry, and selling when the close is at a seven-day high. Notably, there is no stop loss, making it a relatively simple strategy.
The strategy is implemented by buying on dips (when the close is at a seven-day low) and selling on strengths (when the close is at a seven-day high). It is considered a mean-reversion strategy because it takes advantage of market movements toward the mean or average price.

The double seven strategy is one of the strategy revealed by Larry Connors and Cesar Alvarez in their book Short Term Trading Strategies That Work. This simple system worked very well on a wide range of ETFs around the time the book was published in 2010. So, it would be interesting to know how it has performed in the last decade since its publication. Here, we will examine the performance of the double seven trading strategy over the last twenty-one years on a wide range of liquid ETFs.
However, the high win ratio is hampered by the fact that the losers are bigger than the winners: 2.99% against 2.06%. Nonetheless, the profit factor is a solid 2.58 and the Sharpe Ratio is 1.4. Moreover, even the maximum drawdown of 33% is much lower than that of the buy-and-hold method, which is 55%.
We also tested the double seven strategy on all the above-mentioned ETFs as one portfolio. By allocating 20% of the equity to each position, we have a maximum of five positions at any time. The results of our backtesting were as follows: 1189 trades with an average gain of 0.63% per trade (excluding slippage and commissions).
It appears that the double seven trading strategy still performs well on the main stock indices. And, it may be possible to tweak it to perform even better. Being a mean-reversion strategy, you can only use it for short-term swing trading.
The double seven strategy, introduced by Larry Connors and Cesar Alvarez, is a mean-reversion strategy that involves buying on dips and selling on strengths. It relies on specific criteria, including closing above the 200-day moving average and a seven-day low. Unlike traditional approaches, it aims to exploit short-term market fluctuations.
The strategy has shown consistent performance over the last decade. Key criteria include the price closing above the 200-day moving average, a close at a seven-day low triggering a long position, and selling when the close is at a seven-day high. It operates as a mean-reversion strategy without using stops.
Another problem for double Seven relationships is that both tend to be impulsive and irreverent, often saying and doing whatever brings relief in the heat of the moment. During arguments things are said which cannot be unsaid, and feelings may be irreparably hurt by either. Both can be insensitive, self-centered, and unreliable. Both tend also to crave constant stimulation which can lead to a hectic social life. This can be exciting if both parties do things together, but if they begin to have separate interests and different sets of friends, their social lives will pull them apart. They may begin to have little time for each other or for their family. Someone is bound to feel left out, and on some level, each Seven is determined that it will not be him.
A seventh born girl born from a seventh child of a magic family is expected to have great powers but they do not manifest. Eventually she's sent to a school for people without magic and learns she can weave through a computer. She and her friend work to save the world from a dangerous nothing that consumes magic. Before or after this she's taken to another world to be coached on how to work her powers by an old man who calls her Catori (sometimes).
Thus says Cheveyo: mage, teacher, the first person in Thea's life to remain unimpressed by her lineage as Double Seventh, the seventh child of two seventh children. From birth, great things were expected of Thea, gradually replaced by puzzled disappointment as it became evident her magical abilities are, at most, minimal. Now, with Cheveyo, Thea has begun to weave herself a new magical identity, infused with elements of the original worlds where Cheveyo and others like him walk. But back home, she attends the Academy, the one school on earth for those who, like her, can't do magic.

It is at the Academy that Thea realizes she will indeed have to fight, since her enemies are hungrier and more dangerous than she thought. What's more, her greatest strength may be the very powerlessness she has resisted for so long.
All in all, the Native American elements were interesting, but an awkward blend with the later scenes in Thea's school and the computer magic. Her ability to access other worlds through computers seemed sort of contrived and random--I guess since in her world, she and computers were both supposed to be unmagical, that somehow allowed her to use them to access her otherworldly powers?
