Hello,
Here is the code of my problem, I am not a very nice programmer so please kindly adjust, what I am trying to do is to have multiple criteria defined for buy and sell signals.
I have multiple candle stick patterns MORNING START, ENGULFING BULL, KICKER etc defined in AFL with combination of multiple indicators, MACD, RSI, ADX etc.
For now BuyEvent1, BuyEvent2, BuyEvent3 and BuyEvent4 are the defined buy signals.
Same with sell, SellEvent1, SellEvent2, SellEvent3 and SellEvent4 are the 4 different criteria for sell signal.
Behind these variables the buy and sell signals are defined.
/////
BuySignal = (BuyEvent1) OR (BuyEvent2) OR (BuyEvent3) OR (BuyEvent4);
SellSignal = (SellEvent1) OR (SellEvent2) OR (SellEvent3) OR (SellEvent4);
//Only one of these buy or sell signal should be applicable for any bar.
/////
Now for generating signals, instead of using flat signal criteria and then removing excessive signals by using ExRem, I have to keep track of each signal since each signal might be of any criteria defined above. So I am using a loop and check status of last signal (buy/sell), If there wasn't any buy signal earlier then no sell signal will be generated. Same for sell signal.
/////
Sell = 0;
Buy = 0;
BP =0; //Buy Price
SP =0; //Sell Price
BuyACTION = 0; //Individual Buy Action
SellACTION = 0; //Individual Sell Action
for( i = 0; i < BarCount; i++ )
{
global X;
X = Cum(BuySignal); //Total number of buy signals.
global BP;
global SP;
global Y;
global U;
global Z;
SP = 0;
BP = 0;
LastSignal = 0; //Keep track of last signal type, Buy or Sell. 0 = initial, 1 = buy, 2 = sell.
Z = 1; //Buy signal counting, starting from 1.
U = 1; //Sell signal counting strating from 1.
//Define first buy signal
if( X[i] == z AND LastSignal[i] == 0)
{
BuyACTION[i] = BuySignal[i];
ExRemSpan( BuyACTION, SellACTION);
Lastsignal = 1;
Z++;
if (BuyACTION[i]){ BP = ValueWhen (BUYACTION,BuyPrice);}
}
else { BuyACTION[i] = 0 AND Lastsignal = 0;}
//Check if a buy signal was defined earlier and then define first sell signal
if( X[i] == U AND LastSignal[i] == 1)
{
SellACTION[i] = SellSignal[I];
LastSignal = 2;
SellACTION = ExRem(SellACTION,BuyACTION);
if (SELLEVENT[i]){ SP = ValueWhen(SellACTION,SellPrice);}
BuyBarPlus2[i] = BarsSince(BuyACTION) >=2;
//Start sell signal after 2 bars from buy signal.
}
else {Lastsignal = 0 AND SellACTION[i] = 0;}
//Check if a sell signal was defined earlier and then define next buy signal
if( X[i] == z AND Lastsignal[i] == 2)
{
BuyACTION[i] = BuySignal[i];
Lastsignal = 1;
BuyACTION = ExRem(BuyACTION,SellACTION);
Z++; U++;
if (BuyACT[i]){global BP; BP = ValueWhen (BUYACT,BuyPrice);}
}
else { LastSignal = 0;}
//Check if a buy signal was defined earlier and then define next sell signal
if( X[i] == U AND LastSignal[i] == 1)
{
SellACTION[i] = SellSignal[i];
SellACTION = ExRem(SellACTION,BuyACTION);
Lastsignal = 2;
if (SellSignal[i]){ SP = ValueWhen(SellACTION,SellPrice);}
BuyBarPlus2[i] = BarsSince(BuyACTION) >=2;
//Start sell signal after 2 bars from buy signal.
}
else {LastSignal = 1; }
}
Buy = BuyACTION;
Sell = BuyBarPlus2 AND SellACTION;
After this just for visual presentation, I plot shapes, prices and assign number to each signal. Variables like BP, SP are used in plotting. Eveyting is ok in that.
The problem is, for both buy and sell signal the system continues to use the very first criteria met, for example if the first buy signal was with BuyEvent3 then all buy signals are of BuyEvent3 criteria, and if the first sell signal was of SellEvent1 then all next sell signals are of SellEvent1 criteria. My purpose for each bar selecting any one of multiple criteria defined dosent get fulfilled.
I tried to keep the code short and relevant to post here.
How to fix it?
Thanks
