// RSI Strategy that buys the dips, uses Price Averaging and Pyramiding.
// When the price drops below specified percentages of the price (8 PA layers), new entries are openend to average the price of the assets.
// Open entries are closed by a specified take profit.
// Entries can be reopened, after closing and consequently crossing a PA layer again.
// This strategy is based on the RSI+PA+DCA strategy I created earlier. The difference is the way the Take Profit is calculated.
// Instead of directly connecting the take profit limit to the decreasing average price level with an X percent above the average price, 
// the take profit is calculated for a part on the decreasing average price and for another part on the deduction 
// of the profits of the individual closed positions.
// The Take Profit Limit drop less significant then the average price level and the full position only completely exits 
// when enough individual closed positions made up for the losses.
// This makes it less risky and more conservative and great for a long term trading strategy
