Position size optimizer RNR_0

// 1. When market volatility is severe, the use of equal weight systems is eliminated.
// 2. It is a bad strategy to concentrate bets since they drive the short position, which ultimately influences the whole book of trade.
// 3. Expect your short positions to get squeezed by at least 10% during the next five trading days.
// 4. When there are bear markets, the correlation goes to 1. Allow for the fact that both Longs and Shorts will go against you at the same time.
// 5. Unprofitable trades increase in magnitude rapidly.
// 6. Unlike in an up-trending market, there are no 2-3 wins. Winners shrink and contribute less. So, there is an opposite tendency toward oversized positions.
// 7. In contrast to a bull market, in contrast to the long. The winners shrink in size and contribute less. As a result, there is an inverse trend toward oversized positions.
// 9. The winners shrink in size, while the losers grow exponentially The challenge is to size positions in such a manner that they contribute favorably when successful but do not completely obliterate performance when unsuccessful.
