ATR Trailing Stop: Convert Thinkscript to Easylanguage

July 4th, 2014, 05:45 AM

Hi, I'm new to easylanguage and having a really rough time changing over from ToS to Multicharts. I dont use any complex strategies and have never had to program in thinkscript so I'm generally new to programming as well.

I was hoping someone could please please help me convert this Thinkscript code for an ATR trailing stop to Easylanguage for multicharts.

I am specifically looking for an Indicator that will plot the ATR stops on my chart regardless of whether or not I have an actual market position (For instance, ToS assumes I have a hypothetical long when starting the plot and this is fine; i.e. no need for an actual position). I am not looking for a signal as these are already programmed into multicharts but for some reason dont plot.

Alternatively, since the below code has customization for modified ATR stops aswell which I'm not interested in, if anyone has their own version of a standard ATR Trailing stop indicator I would really appreciate that as well!

Please help!

input trailType = {default modified, unmodified};
input ATRPeriod = 5;
input ATRFactor = 3.5;
input firstTrade = {default long, short};

assert(ATRFactor > 0, "'atr factor' must be positive: " + ATRFactor);

def HiLo = Min(high - low, 1.5 * Average(high - low, ATRPeriod));
def HRef = if low <= high[1]
then high - close[1]
else (high - close[1]) - 0.5 * (low - high[1]);
def LRef = if high >= low[1]
then close[1] - low
else (close[1] - low) - 0.5 * (low[1] - high);
def ATRMod = ExpAverage(Max(HiLo, Max(HRef, LRef)), 2 * ATRPeriod - 1);

def loss;
switch (trailType) {
case modified:
loss = ATRFactor * ATRMod;
case unmodified:
loss = ATRFactor * AvgTrueRange(high, close, low, ATRPeriod);
}

def state = {default init, long, short};
def trail;
switch (state[1]) {
case init:
if (!IsNaN(loss)) {
switch (firstTrade) {
case long:
state = state.long;
trail = close - loss;
case short:
state = state.short;
trail = close + loss;
}
} else {
state = state.init;
trail = Double.NaN;
}
case long:
if (close > trail[1]) {
state = state.long;
trail = Max(trail[1], close - loss);
}
else {
state = state.short;
trail = close + loss;
}
case short:
if (close < trail[1]) {
state = state.short;
trail = Min(trail[1], close + loss);
}
else {
state = state.long;
trail = close - loss;
}
}

def BuySignal = Crosses(state == state.long, 0, CrossingDirection.Above);
def SellSignal = Crosses(state == state.short, 0, CrossingDirection.Above);

plot TrailingStop = trail;

TrailingStop.SetPaintingStrategy(PaintingStrategy.POINTS);
TrailingStop.DefineColor("Buy", GetColor(0));
TrailingStop.DefineColor("Sell", GetColor(1));
TrailingStop.AssignValueColor(if state == state.long
then TrailingStop.color("Sell")

I am trying to find the same thing. I have looked everywhere for ATR trailing stop indicator for tradestation, and can only find a strategy, not an indicator.

Here is a basic ATR stop indicator.. for multicharts (not tested in TS), not sure who the author is either...

Code

Inputs: Price(Close),atrPeriod(14),atrMult(1.75);
    
Vars:
    atr(0), ts(0), shstp(0), lgstp(0), trend(0), TriggerPrice(0), dir(0);
    
atr = AvgTrueRange(AtrPeriod);

lgstp = Price - atr * atrMult;
shstp = Price + atr * atrMult;

TriggerPrice = close; 

if TriggerPrice >= ts[1] then
    trend = 1
else if TriggerPrice < ts[1] then
    trend = -1;

if trend > 0 then
    if trend[1] < 0 then ts=lgstp[0]
    else if lgstp >= ts[1] then ts=lgstp[0]
    else ts=ts[1];

if trend < 0 then
    if trend[1] > 0 then ts=shstp[0]
    else if shstp <= ts[1] then ts=shstp[0]
    else ts=ts[1];

Plot1(ts,"Long Stop");
Plot2(ts,"Short Stop");
Plot3(ts,"ATR Stop",iff(trend = 1,GetPlotColor(1),GetPlotColor(2)));

How do I turn code below into system so it buys/sells when it changes direction?

And what does ts in the code mean?

Many thanxx

It's NOT my code so my "Guess" would be that TS stands for "Trailing Stop"...

Here is a simple conversion from the stop indicator to a basic system...(untested and not my code).

Code

Inputs: Price(Close),atrPeriod(14),atrMult(1.75);
    
Vars:
    atr(0), ts(0), shstp(0), lgstp(0), trend(0), TriggerPrice(0), dir(0);
    
atr = AvgTrueRange(AtrPeriod);

lgstp = Price - atr * atrMult;
shstp = Price + atr * atrMult;

TriggerPrice = close; 

if TriggerPrice >= ts[1] then
    trend = 1
else if TriggerPrice < ts[1] then
    trend = -1;

if trend > 0 then
    if trend[1] < 0 then ts=lgstp[0]
    else if lgstp >= ts[1] then ts=lgstp[0]
    else ts=ts[1];

if trend < 0 then
    if trend[1] > 0 then ts=shstp[0]
    else if shstp <= ts[1] then ts=shstp[0]
    else ts=ts[1];

if trend[1] < 0 and trend >= 0 then buy next bar at market;
if trend[1] > 0 and trend < 0 then sellshort next bar at market;

Thank you!!!

Do you know where I can find more code like this?

Loop,

you can find a lot via google for example. Multicharts also has a lot build in and a knowledge-base with code on their website as well as the forum.

Besides that the elite section here on futures.io offers tools for Multicharts for download, too.
