LNL 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 consist of two components - the Trend Line and the Stop Line. Trend System is based on a special ATR calculation that is achieved by combining the previous values of the 13 EMA in relation to the ATR which creates a line of deviations that visually look similar to the basic moving average but actually produce very different results ESPECIALLY in sideways market.

Hi Samer,

Is there a way incorporate this to Scan. like Bullish and Bearish .. I tried though but unable to pick the value? can you please develop scan based on the Trend or Stopline parameters

Hi Samer,
Thank you so much for scan. Appreciate your help

Author Message:
LNL 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 consist of two components - the Trend Line and the Stop Line. Trend System is based on a special ATR calculation that is achieved by combining the previous values of the 13 EMA in relation to the ATR which creates a line of deviations that visually look similar to the basic moving average but actually produce very different results ESPECIALLY in sideways market.

-Just a heads up the term for several day trading is swing trading/trader
-It looks like you just select whatever time frame you want to use on thinkorswim and it'll adjust automatically

I am going to set up this scan. In the Scan set up, do I just click "false" under the bull "plot" selection to get a bear condition. Or do I have to change the script? Thanks again Samer for all your expertise.

For bear scan
change this:
#plot Bear = if bearCond within 3 bars then high else na;
to this:
plot Bear = if bearCond within 3 bars then high else na;
 
Hey Samer, thank you for sharing this! I noticed on $SPX the dash marks above and below each candle don't show up on any time frame. However, it does on $SPY. Not sure if this is fixable but thought I would throw it out there. It seems to work on every other ticker I've looked at it on though.

You are correct.
Given that there is no volume associated with $SPX, no indicator that uses volume in its calculations will work correctly on $SPX

Author Message:
LNL 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 consist of two components - the Trend Line and the Stop Line. Trend System is based on a special ATR calculation that is achieved by combining the previous values of the 13 EMA in relation to the ATR which creates a line of deviations that visually look similar to the basic moving average but actually produce very different results ESPECIALLY in sideways market.

Hi Samer, I have tried this indicator recently and it worked well. How to set up sound alert and backtesting, such as when price close above / below StopLine and StopLine2? Thanks.

Append the following to the end of your script:

Alerts For Price Crosses StopLines

# Alerts
Alert(close crosses above StopLineNETtf1, "Price crossing above StopLine1", Alert.Bar, Sound.Chimes);
Alert(close crosses below StopLineNETtf1, "Price crossing below StopLine1", Alert.Bar, Sound.Bell);
Alert(close crosses above StopLineNETtf2, "Price crossing above StopLine2", Alert.Bar, Sound.Chimes);
Alert(close crosses below StopLineNETtf2, "Price crossing below StopLine2", Alert.Bar, Sound.Bell);
