Hi friends,

In almost every type of price action trading drawing support/resistance line for the current timeframe and higher timeframe is required. Automated drawing of the same does not serve the purpose well.

Here is a AFL which will alert when price approach or touch (with definable proximity) the support/resistant line manually drawn by you at any place on the chart.

Please check and apply it as explained in the AFL.

I have tried it (AB ver. 5.50) with no result. Could not understand what is going wrong!

Help is required !!

Thanks :)

This System finds stocks, where the price reached a support or resistance line, that you have manually drawn.
You must give every line any of these 6 predifined StudyID's
(RE,SU,UP,DN,RI,ST). The system automaticaly detects, if the line is currently a support or resistance line.

There are two modes: Modus == 0; I called it "after touching" , because you become the signal after the stock has touched any support or resistance line.Adjustment for touching is "ALvalue and AHvalue" With ALvalue you can define, how near the Low must go to any support line, equivalent AHvalue to resistance line, before a signal is given.

With Modus == 1 "bLvalue and bHvalue" you can detect stocks, where the price is before touching any line, so you mostly can find signals for the next trading day and so you have enough time to check other arguments and then you can buy at the exact support Level or sell at the exact resistance level.


Cross_buy_value = 1.03; Cross_sell_value = 0.97;
Here you can define the value, where the price must reached, before a signal would be generated. For example: 1.03 means that a buy signal is given, when the price is 3% above the last resistance. equivalent the cross_sell_value.


With the Explore Function you can see the distance from the current close to all support and resistance lines in percent.
Re = Resistance Su = Support

In the indicator window you can see the close and all your study's (currently 6 study's possible).
So you can quickly see, if you've forgotten to give a study ID to any line.


Attention: Dont forget, that the back-test brings unrealistic results, because the signals only real at the time that you've drawn the study.
Also dont forget in the explore window, that only the resistance and support distances are shown, that you have drawn and defined with a study ID.


So enjoy it!

I am not getting any script after exploring...

With the Explore Function you can see the distance from the current close to all support and resistance lines in percent.
Re = Resistance Su = Support

See here I am inserting a horizontal line within the body of the last candle then giving it a Study ID (RE) and exploring...but I am not getting any script name

In the indicator window you can see the close and all your study's (currently 6 study's possible).
So you can quickly see, if you've forgotten to give a study ID to any line.

Calls to Study function on Line 17-18 are incomplete. You need to specify the Chart ID like this

Code: 
L1 = Study ("SU", GetChartID());
L2 = Study ("RE", GetChartID());
...
Also, get rid of all the Plot functions at bottom of script

Finally to verify the values, use following and do delete it once its working
Code: 
Title = "L1 = " + NumToStr(L1, 8.3, True) + "RE = " + NumToStr(L2, 8.3, True);
Lastly, I don't think Explorer works by relying on things plotted on Charts ... I mean explorer does not plot the chart to do the scanning. All plotting related functions are ignored by scanner/explorer. If you want explore, provide it as % off price or specify it as parameters and run over all stocks in same price bracket.
