EasyLanguage Code for Pyramiding a Day-Trading System w/video [PART-2]


Check out the latest video on Pyramiding.

Here is the finalized tutorial on building the pyramiding ES-day-trade system that was presented in the last post.

I will admit this video should be half as long as the end result.  I get a bit long-winded.  However, I think there are some good pointers that should save you some time when programming a similar system.

EasyLanguage Source:

Here is the final code from the video:

vars: mp(0),lastTradePrice(0),canSell(true);

mp = marketPosition * currentContracts;

if date[0] <> date[1] then
	canSell = true;  // canSell on every day

if mp = -1 then canSell = false; // one trade on - no more
if time > 1430 then canSell = false; //no entries afte 230 central

if mp = 0 and canSell = true then sellShort next bar at OpenD(0) - 3 stop;

if mp = -1 then sellShort next bar at OpenD(0) - 6 stop; //add 1
if mp = -2 then sellShort next bar at OpenD(0) - 9 stop; //add 2

if mp = -1 then lastTradePrice = OpenD(0) - 3; //keep track of entryPrice
if mp = -2 then lastTradePrice = OpenD(0) - 6;
if mp = -3 then lastTradePrice = OpenD(0) - 9;

if mp <> 0 then buyToCover next bar at lastTradePrice + 3 stop; // 3 handle risk on last trade

// next line provides a threshold prior to engaging trailing stop
if mp = -3 and barsSinceEntry > 0 and lowD(0) < lastTradePrice - 3 then buyToCover next bar at lowD(0) + 3 stop;

EasyLanguage for Pyramiding and Day-Trading ES

What we learned here:

  • can’t use entriesToday(date) to determine last entry price
  • must use logic to not issue an order to execute on the first bar of the next day
  • mp = marketPosition * currentContracts is powerful stuff!

In the next few days, I will publish the long side version of this code and also a more eloquent approach to the programming that will allow for future modifications and flexibility.

Let me know how it works out for you.

Take this code and add some filters to prevent trading every day or a filter to only allow long entries!

Don’t Fool Yourself – Limitations of Back Testing with Daily Data [EasyLanguage]

Which equity curve do you like best? (created with EasyLanguage script) This one…

Or this one?

Obviously the first one.  Even though it had a substantial draw down late in the test.  What if I told you that the exact same system logic generated both curves?  Here is the EasyLanguage code for this simple system.

Buy next bar at open of next bar + .25 *avgTrueRange(10) stop;
Sellshort next bar at open of next bar - .25*avgTrueRange(10) stop;

Open Range Break Out with Profit and Loss Objective

This algorithm relies heavily on needing to know which occurred first: the high or the low of the day.   The second chart tells the true story because it looks inside the daily bar to see what really happened.  The first chart uses an algorithm to try to determine which happened first and applies this to the trades.  In some instances,  the market looks like it opens then has a slight pull back and then goes up all day.  As a result the system buys and holds the trade through the close and onto the next day, but in reality the market opens, goes up and triggers a long entry, then retraces and you get stopped out.  What was a nice winner turns into a bad loss.  Here is an example of what might have happened during a few trades:

Nice flow – sold, bought, sold, bought, sold again and finally a nice profit.  But this is what really happened:

Sold, bought, reversed short on same day and stopped out on same day.  Then sold and reversed long on same day and finally sold and took profit.   TradeStation’s Look Inside Bar feature helps out when your system needs to know the exact path the market made during the day.  In many cases, simply clicking this feature to on will take care of most of your testing needs.  However, this simple algorithm needs to place or replace orders based on what happens during the course of the day.  With daily bars you are sitting on the close of the prior day spouting off orders.  So once the new day starts all of your orders are set.  You can’t see this initially on the surface, because it seems the algorithm is so simple.   Here is another consequence of day bar testing when the intra-day market movement is paramount:

Here the computer is doing exactly what you told it!  Sell short and then take a profit and sell short 25% of the ATR below the open.  Well once the system exited the short it realized it was well below the sell entry point so it immediately goes short at the exact same price (remember TS doesn’t allow stop limit orders).  You told the computer that you wanted to be short if the market moves a certain amount below the open.  These were the orders that were place on yesterday’s close  This may not be exactly what you wanted, right?  You probably wanted to take the profit and then wait for the next day to enter a new trade.  Even if you did want to still be short after the profit level was obtained you wouldn’t want to exit and then reenter at the same price (practically impossible) and be levied a round-turn slip and commission.   You could fiddle around with the code and try to make it work, but I guarantee you that a system like this can only be tested properly on intra-day data.  Let’s drop down to a lower time frame, program the system and see what the real results look like:

Looks very similar to the daily bar chart with Look Inside Bar turned on.  However, it is different.  If you wan’t to gauge a systems potential with a quick program, then go ahead and test on daily bars with LIB turned on.  If it shows promise, then invest the time and program the intra-day version just to validate your results.  What do you mean spend the time?  Can’t you simply turn your chart from daily bars to five minute bars and be done with it.  Unfortunately no!  You have to switch paradigms and this requires quite a bit more programming.  Here is our simple system now in EasyLanguage:


{Use highD() and XXXXD(0)  functions to capture the highs, lows, and closes for the past 10 days.  
 I could have just used a daily bar as data2.  
 I am looking at five minute bars so we know how the market flows through the day.

{This loop kicks out a warning message, but seems to work
 Just do this once at the beginning of the day - faster}

{remember true range is either the higher of todays high
 Or yesterdays close minus the lower of todays low or 
 yesterdays close}

{ tradeStation time stamps at the close of the bar so
 we capture the opening of the open time plus the bar interval - 
 in this case 5 minute - so at 1800 + 5 (1805) I capture the open
 of the day}

if time = sess1StartTime + barInterval then  
	Value1 = 0.0;
	for icnt = 1 to 10
		Value1 = value1 + maxList(closeD(icnt-1),highD(icnt)) - minList(closeD(icnt-1),lowD(icnt));
	atr = value1/10.0;
	stb = open + .25* atr;
	sts = open - .25* atr;
	buysToday = 0;
	sellsToday = 0;

mp = marketPosition; {The ole mp trick}

If mp = 1 and mp[1] <> 1 then buysToday = buysToday + 1;
If mp =-1 and mp[1] <> -1 then sellsToday = sellsToday + 1;

if buysToday = 0  and time < sess1EndTime and close <= stb then buy next bar at stb stop;
if sellsToday = 0 and time < sess1EndTime and close >= sts then sellshort next bar at sts stop;

Open Range Break Out Utilizing Five Minute Bars

Here is a validation that Look Inside Bar does work:

This is the trade from June 1st.  Scroll back up to the second chart where LIB is turned on.

Original Camarilla EasyLanguage Code

Camarilla – A group of confidential, often scheming advisers; a cabal.


I wanted to elaborate on the original version of Camarilla.  The one that users have been downloading from this website is pure reversion version.  The Camarilla Equation was by created by Nick Scott, a bond day trader, in 1989.  The equation uses just yesterday’s price action to project eight support/resistance price levels onto today’s trading action.  These levels, or advisers, as the name of the equation suggests provides the necessary overlay to help predict turning points as well as break outs.  Going through many charts with the Camarilla indicator overlay it is surprising how many times the market does in fact turn at one of these eight price levels.  The equations that generate the support/resistance levels are mathematically simple:


Resistance #4 = Close + Range * 1.1 / 2;

Resistance #3 = Close + Range * 1.1/4;

Resistance #2 = Close + Range * 1.1/6;

Resistance #1 = Close + Range * 1.1/12;


Support #1 = Close – Range * 1.1/12;

Support #2 = Close – Range * 1.1/6;

Support #3 = Close – Range * 1.1/4;

Support #4 = Close – Range * 1.1/2;


The core theory behind the equation and levels is that prices have a tendency to revert to the mean.  Day trading the stock indices would be easy if price broke out and continued in that direction throughout the rest of the day.  We all know that “trend days” occur very infrequently on a day trade basis; most of the time the indices just chop around without any general direction.  This is where the Camarilla can be effective.  Take a look at the following chart [ ES 5-minute day session] where the indicator is overlaid. and how the strategy was able to take advantage of the market’s indecisiveness.  This particular example shows the counter-trend nature of the Camarilla.  The original Camarilla looked at where the market opened to make a trading decision.  The chart below is an adapted version of the one I send out when one registers on for the download.   I thought it would be a good idea to show the original that incorporates a break out along with the counter trend mechanism.  I will go over the code in the next post.  You can copy the code below and paste directly into you EasyLanguage editor.

Camarilla at its Best!
Carmarilla in Reversion Mode

Original Camarilla rules:

  • If market opens between R3 and R4 go with the break out of R4.  This is the long break out part of the strategy.
  • If market opens between R3 and S3 then counter trend trade at the R3 level.  In other words, sell short at R3.  If the market moves down, then buy S3.  As you can see this is the mean reversion portion of the strategy.
  • If market open between S3 and S4 go with the break out of S4 – the short break out method.
  • Stops are placed in the following manner:
    • If long from a R4 break-out, then place stop at R3.
    • If short from a S4 break-out, then place stop at S3.
    • If long from a R3 countertrend, then place stop at R4.
    • If short from a S3 countertrend, then place stop at S4.
  • Profit objectives can be placed at opposite resistance/support levels:
    • If short from a R3 countertrend, then take profits at S1, S2, or S3.
    • If long from a S3 countertrend, then take profits at R1, R2, or R3.

Profit objectives for all trades can be a dollar, percent of price of ATR multiple.

Camarilla Strategy EasyLanguage Source

Using Strings in EL for multi-step System

This little strategy uses EasyLanguage’s string manipulation to keep track of a multi-step, mutli-criteria, multi-state trade entry. You don’t buy until the buyString is equal to “BUY”. The sell side is just the opposite. When you program a multi-step entry you also need to build a reset situation. In the case of this system you reset the string to null(“”) when the price dips back down below the 9 day moving average. After resetting the process starts over again.

{Use curly brackets for mult-line
 This system needs three criteria to be met
 before a trade is initiated
 Buy Criteria 1:  C > 9 day movAvg - trend Up
 Buy Criteria 2:  H = HighestHigh 10 days - break Out
 Buy Criteria 3:  C < C[2] - retracement }
 if marketPosition = 0 then {If flat then reset strings}
 	buyString = "";
 	sellString = "";
 if c >= average(c,9) then buyString = "B";  //First criteria met
 if c < average(c,9) then buyString = "";
 if c > average(c,9) then sellString = "";
 if c <= average(c,9) then sellString = "S"; 
 if buyString = "B" then
 	if h > highest(h,10)[1] then buyString = buyString + "U"; //Second Criteria met
 if buyString = "BU" then
 	if c < c[2] then buyString = buyString + "Y"; //Third criteria met
 if buyString = "BUY" then buy ("BuyString") next bar at open; //Read BUY
 if sellString = "S" then
 	if l > lowest(l,10)[1] then sellString = sellString + "E";
 if sellString = "SE" then
 	if c > c[2] then sellString = sellString + "LL";
 if sellSTring = "SELL" then sellShort ("sellString") next bar at open;
