Stuck on retrieving previous bid prices by each second?

New comment

Hi, im stuck on how to retrieve previous bid prices by each second and then compare them for further use.

Using : double curBid = MarketInfo(_Symbol,MODE_BID);

I can find current bid of every second no problem but how can I find previous values like for example I can on the 1m timeframe using :

double high = High[iHighest(_Symbol,_Period,MODE_HIGH,3,0)]; It can only understand finding each previous bar but seconds i cant find a way?


Thanks for any help



Because there is no way, ticks are not stored. If you want it you will have to store them (in a circular buffer:)

#define MAX_BACK 60
double bids[MAX_BACK]; int lastBid=0;
double getBid(int iPast){  
   return bids[ (lastBid + iPast) % MAX_BACK ];                                }
void   putBid(double v){ 
   lastBid = (lastBid-1+MAX_BACK)%MAX_BACK;   bids[lastBid]=v;                }
void OnTimer(void){     putBid(Bid);                                           }
int OnInit(void){       EventSetTimer(1);                                      }
:
double bid2SecondsAgo = bid(2);

If you want price changes (not seconds) ago, use OnTick instead of OnTimer. You might want to store time stamp as well as bid.
