Amibroker: How to Plot ApplyStop on a Chart

Line1

Beginners Course  |  Intermediate Course  |  Amibroker Course Home

We recently looked at the ATR Trailing Stop Loss and how to code it in Amibroker, as used by thousands of traders over a number of decades.

More often than not, we want to actually see our stop loss on the chart, so we know if we have coded it correctly and if it is having the impact we want it to on our trading system.  Plotting part of our trading system on a chart can also help us “debug” it, if it’s not acting correctly or doing what we want, we can see it straight away.

Normally, Plotting a line on a chart would be a fairly easy process.  However if we want to show our stop loss correctly, we have to take things up a notch and add some new pieces of code so that we:

  • Only show the stop loss when we are in a trade
  • Ensure it reflects our exact buy and sell signals

That’s where this video comes in.  Check it out, to learn how to Plot any ApplyStop function in the future!

I hope you enjoy, and please leave a comment below 🙂

The first part of our code is:

  • Equity( 1, 0 );

Which evaluates the stops, over all quotes.  Next we need to tell Amibroker when we are in a trade, using our “light switch”, the Flip() function.  This function is really cool.

  • InTrade = Flip( Buy, Sell );

From there we need only three things:  To check that there are no “Null” bars (this would throw off our stop loss), set up the Array that we will use to plot our stop loss line, and the use Plot() to plot that array on the chart along with PlotShapes to show our buy and sell arrows.

Hope you enjoyed, and happy trending!

    Hi Dave,

    You recommend the use of the function Equity to plot ApplyStop. However the description page of the function says:
    This function is left here for backward compatibility and is using old, single-security backtester. New coding should rather use portfolio-level equity (special ~~~EQUITY ticker).

    Would you like to comment please. What should be the updated way of doing the same?

    Thanks,
    Neha

    Hey Neha,

    Wow, good question. I checked it out. Looks like the Equity() function is called the “older” one, but still used for individual stocks (such as plotting a single stock’s stop loss).

    The other “new” method is using the ~~~EQUITY symbol (you can search for it in your ticker window). This symbol generates afresh every time you do a back-test, and shows you your Portfolio Equity (including the effect of multiple positions, position sizing, missed trades, etc).

    You can actually calculate Portfolio level equity using the “old” Equity(), if anyone ever wanted to – Herman Van Den Bergen gave some code for this at- amibroker.com/guide/a_equity.html

    Thanks for the question! That helped me too.

    Happy trending,

    Dave

    Dave,

    Thank you once again. Seems like just for plotting ApplyStop purpose, the Equity() seems to be doing fine. Thanks once again.

    Happy Trending to you too 🙂

    No problems 🙂 I should also say – if anyone knows better, please feel free to post!

    I have no problems being corrected, because it means we all get the right info 🙂 But it seems to work well.

    Hi Dave,
    Your website is very easy to learn for new Amibroker user. I have a few problem with coding. Do you have email address to contact ? It would be appreciated if you can help me and I think some people may have the same problem.

    Thx,
    Sarids
