// L&L Trend System
//
// L&L Trend System is an ATR based day trading system specifically designed for intra-day traders and scalpers.
//
// The System works on any chart time frame & can be applied to any market. The study involves two components: 1.) Trend Line which is basically a fast gauge
// represented by the 13 EMA. 2.) Stop Line is an ATR deviaton line with special calculation based on the previous bar ATRs and position of the price in relation
// to the current and previous values of 13 EMA.
//
// There are 5 different trend modes available. Each mode is visualizing different ATR settings which provides either aggressive or more conservative approach. The
// more "tigher" modes such as tight or normal can be used on less volatile markets such as S&P Futures (ES). Looses & FOMC modes are designed for active high volatility
// markets such as NQ or YM futures or BTC or perhaps some currency pairs. Then there is the "Net" mode. The net mode is basically the combination of all modes in one
// stop line system which creates "the net" effect. The system also includes additional higher time frame (HTF) trend system. This can be set to any time frame by manual
// HTF mode. HTF mode set to "auto" will automatically choose the best suitable higher time frame trend system based on my backtesting results.
//
// By default, the bars are colored (Trend Bars) based on the DMI and ADX indicators. Whenever the DMI is bearish and ADX is above 20 the candles paint themselfs red.
// And vice versa for the green candles and bullish DMI. Whenever the ADX falls below the 20, candles are netural which means there is no real trend in place.
//
// In terms of visualization, each trend system is fully customizable through the inputs settings. There is also an option to turn on/off the background clouds behind the
// stop lines. These clouds can make the charts more clean & visible.

The mods are lined up based on the aggressiveness of the ATR. Tight & Normal modes are the going to flip way much often whereas the Loose or FOMC will provide much higher wiggle room. The good rule of thumb to use is to just stick with first two modes when trading less volatile sessions or ranges, and use the other two on fast moving expanding environments. The Net mode provides the combination of all modes in one giant net. Some might prefer this mode since it suits well to the scale in scale out methods. ')
