indicator to subtract one symbol from another

[brdnickel]

Hi I was wondering if there is an
a. indicator that can subtract two symbols or two indexes...
b. additional add to a histogram ..
for example I would like a histogram plotting new highs minus new lows.
or I would like to form a line froma 30yr yield minus a 3 month yield?
any thoughts would be much appreciated.

Also...I know im pushing it...but is there an indicator that inverts a line...for example the trin or the vix?

thanks dy

dy, those operations could be done with MultiSeries indicators in our NinjaTrader 7 - for ideas and a starting point into this territroy you can check into the custom Spread indicator works shared here from a fellow user - http://www.ninjatrader.com/support/f...=spread&desc=1

Thank you very much!

Bertrand, how do I add a histogram....for example I want to use a histogram for the 52 week highs and lows?
also is there an indicator to invert a line?...thanks a bunch!!

Unfortunately I'm not aware of custom indicator implementations already for those tasks, you would need to custom code them - what do you mean by 'inverting a line'? To take the reciprocal value?

Thank you, the "trin" is an indicator that tracks its line opposite to the market...I want to invert it so that it can track along with it...for easier reading.

Hello brdnickel,

You can invert a value by dividing from 1.

1 / TrinValue.

In an indicator this could be 1 / Close[0]

dont understand how to write for indicators...can I do this under data series or properties?

[NinjaTrader_Bertrand]

Unfortunately not - you would need to custom code / modify the code in the NinjaScript editor.

thank you...and last question today..I go the ratio for two symbols....(i plot two symbols in my chart and then use an indicator to get the ratio). Once I get the ratio, I want to plot a sma 21 period to the "ratio"....not the actual top symbol (which seems to be what is happening since I cannot remove the original symbol)..do you know a way to get the moving average to the ratio?
thanks again. Much appreciated

You would need to input this indicator calculating the ratio into the MA as input series (indicator on indicator principle) -
