help strange problem on scaning nd exlporation

#1
guys i have a formul which shows buy-sell signal.....but when i run scan on it it doesnot scan nd shows a error message that buy-sell signal missing ....why so ?
when i run exlporation it again shows an error by sayng check help how to run exploration................whereas if i expore or scan with other formula it does that very easily..thnx in advance
 
#3
hi bro thnx for reply....but the problem not rectified...now when i add ur line " filter=buy or sell" it shows error in formula that buy nd sell variables used without being intianlised.plz bro if posible write the exact line to be added for scanning nd exploration....thnx

check and make sure that Buy= and Sell= conditions are written in the afl and put the filter= after these Buy/sell lines or as the last line in the afl

guys i am wrting the formula....plz make changes nd make it suitable for scaning nd exploration........thnx

Hi amit, attached pls find the afl with scan and explorer. Pls note in Explore The Red "P" stands for low Pivot and Green P Stands for High Pivot while B stands for low Pivot and Red S stands for High Pivot

hey vinod ji.......thnx a lot for such a prompt reply :clapping:....now its working for both....realy appreciate for ur help:clap:...thnx again.... can u help me some more in learning also....actualy i m a new learner.....i take as scan nd exploration ...more of same...can u tell me the diffrence between them...nd how to make correct use.....
also i am looking for an intra afl with good accuracy...do u have any or u can help me in some way.....if i give u few condtions can u make an afl for that....thnx again....

scanning gives u only buy short signals while exploration can give u any sort of filters u may write in the afl. tell me the conditions

hey vindo ji thnx again:thanx:....u have been realy nice..to help....ok.the comdtions are i have heard that 3 indictors r good for intraday trdng , rsi , macd , moving ave , so i would like that someone can write a formula on these.

BUY signal when all theses 3 condtions satisfied=

1) rsi below 30
2) macd buy signal above zero
3) 20 day moving average( or 20 intraday bars since its intraday) holds or if trdng below it then on its crossover

SELL signal=

1)rsi above 70
2)macd sel signal below 0
3)20 day moving averges breaks


vinod ji i m not sure whether i am even right on the condtions or no...if i am wrong plz correct me or else u can advice somethng else....by the way are u on yahoo messneger also ?
