Hello svadukia,

Thanks for your post.

I would suggest adding the platform indicator "Price line" to your chart. With this indicator you can plot Bid, Ask and Last lines of the live data.

I don't want to plot current Bid and Ask.

I want first take last trade price then see if that happens at bid or ask then take next last trade price and see if it happened at bid or ask.

so after that Want to do Last Ask Trade price Minus Last Bid trade price.

Hope you understand now.

Hello svadukia,

Thanks for your reply.

I'm not sure if you actually looked at the indicator but it will show the last line which will either be at the Bid or the Ask and you will always see the Last line and either the Bid or Ask which shows the difference between the two.

If you look at the Ninjascript code for the Price Line indicator, it pulls the Bid/Ask/Last values from the OnMarketData() method so if you want to create your own indicator, that would show you how to collect the information to analyze. I am unsure how you would want to plot/show/express the difference data.

Hello Paul,

Thank you for your reply.

Checked Price Line indicator. I Want to plot difference as a bar like we plot volume as a bar. Can It be done?

Hello svadukia,

Thanks for your reply.

Yes, it could be plotted as a bar.

You may want to make a copy of the price line indicator and modify it to suit your purposes.
