I am trying to code the following:

The bar has made a lower low

I have tried LLV(L,1) but it doesn’t do what I want. Neither does Outside()

What should I use please?

Ignore me…I’m an idiot!!! Which means of course I found it in the last place I chose to look, which should have been the first place I chose to look

It will ALWAYS be in the last place – you wouldn’t keep on looking for something you’ve already found :woohoo:

You have a very relevant point!

Can someone help with this..

The following statement returns a ARRAY not a number because a array is used in the IIF function.

Maxpos = IIf(IndexUp,10,20);

Is there a easy way to get the result that i’m after? Am i missing something? I need a similar statement to return a number not a array to use in the SetOption(“MaxOpenPositions”,MaxPos);

Cheers

I thought the above would work:

SYNTAX IIf( EXPRESSION, TRUE_PART, FALSE_PART )
RETURNS ARRAY or NUMBER

Why not try “if” which works bar by bar

Code:

for( i = 0; i < BarCount; i++ ) { if( IndexUp[ i ] ) { SetOption("MaxOpenPositions",10);// this part is executed when condition is met } else { SetOption("MaxOpenPositions",20);// this part is executed when condition is not met } }

I tried that but it crashed Ami…

I tried this before it will not work, here is the workaround from what i remember
you set the position number as max 20 in your case and you control the number of positions from the position size
so it should be one thing like this
MaxPos = 20
positionsize=10%
margin = iif(indexup,100,50);

anyhow i will give you the exact workaround later

Rounding Issue
This is the code I am using and I have also tried rounding the round
but a few of the stock I end up with 49.379999 for example
BuyLimVal = round(BuyLimitP/0.01);
BuyLim = BuyLimVal * 0.01;

Workaround???

Try this function

Prec
– adjust number of decimal points of floating point number

Math functions

SYNTAX Prec(ARRAY, precision )
RETURNS ARRAY
FUNCTION Truncates ARRAY to precision decimal places.
EXAMPLE The formula “prec( 10.12981, 2 )” returns 10.120. The formula “prec( 10.12981, 4 )” returns 10.12980.

Multiple exits – “x” (I have used RSI for the example below) OR “exitbars”

I had this code saved before and can’t find it so I am trying to code it again and hitting blanks….I am rusty on the coding and obviously not fully understanding the looping. I will have to revisit that section.

ExitBars = Param(“# Exit Bars”,10,2,100,1);
RSIEx = RSI(14) > 70;
SellSetUp = RSIEx OR ExitBars;
LEx = Ref(SellSetUp,-1);

Short = Cover = False;

//=================================================================================
//Looping
//=================================================================================
Buy = 0;
Sell = 0;
PriceAtBuy = 0;
LBIT = 0;
FlagExit = 0;
//=================================================================================

for (j = 1; j < BarCount; j++)
{
if (PriceAtBuy==0 AND LE[j])
{
Buy[j] = True;
BuyPrice[j] = LEPrice[j];
PriceAtBuy = BuyPrice[j];
LBIT[j] = 1;

if (LBIT[j] > 1 AND (LEx[j] OR OnSecondLastBarOfDelistedSecurity[j]))
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}
}
else
if (PriceAtBuy > 0)
{
LBIT[j] = LBIT[j-1] + 1;
if (LBIT[j] > 1 AND (LEx[j] OR OnSecondLastBarOfDelistedSecurity[j]))
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}
if (LBIT[j] == ExitBars)
{
FlagExit[j] = True;
}

if (LBIT[j] > 1 AND (LBIT[j] > ExitBars OR OnSecondLastBarOfDelistedSecurity[j]))
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}
}
}

This is my looping code for Exitbars

Code:

SellSetup = C > Ref(C,-1) OR C < LMA; LEx = Ref(SellSetUp,-1); ExitBars = Param("# Exit Bars",4,1,15,1); Short = Cover = False; //================================================================================= //Looping //================================================================================= Buy = 0; Sell = 0; PriceAtBuy = 0; LBIT = 0; FlagExit = 0; //================================================================================= for (j = 1; j < BarCount; j++) { if (PriceAtBuy==0 AND LE[j]) { Buy[j] = True; PriceAtBuy = LEPrice[j]; BuyPrice[j] = LEPrice[j]; LBIT[j] = 1; } else if (PriceAtBuy > 0)
{
LBIT[j] = LBIT[j-1]+1;

if (LBIT[j] == ExitBars)
{
FlagExit[j] = True;
}

if (LBIT[j] > ExitBars)
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}

if (LBIT[j]>1 AND LEx[j])
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}

if (LBIT[j] >= 1 AND NTEx[j])
{
Sell[j] = True;
SellPrice[j] = C[j];
LPriceAtBuy = 0;
}
}
}
//———————————————————————
LESetUp = IIf(LBIT==0 OR Sell==1,BuySetUp,0); //Long Entry SetUp
LExSetUp = IIf(LBIT>0 AND Sell==0,SellSetup,0); //Long Exit Setup

Add this part at the start of your Entry and Exit signals

Code:

NTPeriod = 30;
DN = DateNum();
LastDate = Status(“rangetodate”);
NT = LastDate – LastValue(DN) >= NTPeriod AND DN == LastValue(DN);
LastBarExit = BarIndex() == LastValue(BarIndex());
NTEx = IIf(NT,LastBarExit,0);

Excellent, thanks Julian. I changed it to the below and it seemed to work, I haven’t been through trades to check if it is doing what it is supposed to do yet.
I will add yours too.

RSIEx = RSI(14) > 70;
SellSetUp = RSIEx;
LEx = Ref(SellSetUp,-1);

Short = Cover = False;
ExitBars = Param(“# Exit Bars”,10,2,100,1);
//=================================================================================
//Looping
//=================================================================================
Buy = 0;
Sell = 0;
PriceAtBuy = 0;
LBIT = 0;
FlagExit = 0;
//=================================================================================

for (j = 1; j < BarCount; j++)
{
if (PriceAtBuy==0 AND LE[j])
{
Buy[j] = True;
BuyPrice[j] = LEPrice[j];
PriceAtBuy = BuyPrice[j];
LBIT[j] = 1;

if (LBIT[j] > 1 AND (LEx[j] OR OnSecondLastBarOfDelistedSecurity[j]))
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}
}
else
if (PriceAtBuy > 0)
{
LBIT[j] = LBIT[j-1] + 1;
if (LBIT[j] == ExitBars)
{
FlagExit[j] = True;
}

if (LBIT[j] > 1 AND (LBIT[j] >= ExitBars OR OnSecondLastBarOfDelistedSecurity[j]))
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}
if (LBIT[j] > 1 AND (LEx[j] OR OnSecondLastBarOfDelistedSecurity[j]))
{
Sell[j] = True;
SellPrice[j] = Open[j];
PriceAtBuy = 0;
}
}
}
