TOS- Plotting Mov Avg. within a buffer zone

February 19th, 2020, 10:09 AM

Hi Folks, I just joined forum. Looking forward to growing my experience with all of you. I'd scoured the web but have struggled to do these 2 things in TOS with thinkscript editor.

1. Plot chart of an adjustment factor/ buffer zone of say +.5% and - .5% around 2 separate mov. averages - a 13 period EMA and a special moving average defined as (O+H+L+2*C)/5. The adjustment factor could change (say be .7% or .8% instead of 0.5% so if it can be chosen/editable would be great). I've attached a picture to try to be clear. So it will chart 3 lines - moving avg line in middle and a green line above .5% and yellow line .5% below the MA. (see attached pic/drawing for clarity)

.

2. Need to add 3 custom columns in say Watchlist (which will be used for trading strategy analysis)- 2 of those columns will be user entered by me- Col 1 =Qty, Col 2 =Purchase price and Col 3= run p/l- will be calculated as Col 1 * (last price- purchase price). I guess, TOS would keep updated last price with realtime quotes; and I should be able to fire alerts off of any of these 3 new custom columns?

That is metatrader :P

The first part or making an indicator is pretty straightforward. The second one I don't think is possible to do with ToS. You might be better off using a spreadsheet for that.

I have used XLS with RTD before but how wud the indicator be handled in thinkscript?

If I understood you correctly, this is what you're looking for:

Code

#
# TD Ameritrade IP Company, Inc. (c) 2007-2019
# Modified by trepidation

input length = 13;
input pctAbove = 0.5;
input pctBelow = 0.5;
input averageType = AverageType.EXPONENTIAL;
def specialFormula = (open+high+low+2*close)/5;

plot Middle = MovingAverage(averageType, close, length);
Middle.setDefaultColor(GetColor(1));

plot Upper = MovingAverage(averageType, specialFormula, length) * (1 + pctAbove/100);
Upper.setDefaultColor(GetColor(6));

Plot Lower = MovingAverage(averageType, specialFormula, length) * (1 - pctBelow/100);
Lower.setDefaultColor(GetColor(4));

0.5%, 5% and settings tab

thanks...I put it in

seems that EMA is working fine but there's no way to pick that special formula (instead of EMA)- unless I'm missing something!

Ah, I see. You said and so I misunderstood what you meant. Here's the updated code. You can toggle between the close or the specialFormula using the useSpecial in the settings page

Code

#
# TD Ameritrade IP Company, Inc. (c) 2007-2019
# Modified by trepidation

input useSpecial = no;
input length = 13;
input pctAbove = 0.5;
input pctBelow = 0.5;
input averageType = AverageType.EXPONENTIAL;
def specialFormula = (open + high + low + 2 * close) / 5;
def formula = if useSpecial then specialFormula else close;
plot Middle = MovingAverage(averageType, formula, length);
Middle.SetDefaultColor(GetColor(1));

plot Upper = MovingAverage(averageType, formula, length) * (1 + pctAbove / 100);
Upper.SetDefaultColor(GetColor(6));

plot Lower = MovingAverage(averageType, formula, length) * (1 - pctBelow / 100);
Lower.SetDefaultColor(GetColor(4));

No - I must not have explained properly

.

it seems to work...I will chekc values later..so I guess the logic is if special is set to yes, then dont use exponential but use special, otherwise use EMA.

What perplexes me is that you only coded NO- so how did system get the yes option?

In the indicator settings, you can choose yes or no as well as change the colors of the plots and adjust the settings.
