Get iMA for the last bar

Dear all,

How can I get the EMA at any of the previous/history bars???

Thanks in Advance.

double Var6 = iMA(NULL, PERIOD_H4, 50, 1, MODE_LWMA, PRICE_MEDIAN, 0);

The last figure, the zero, denotes which bar in history it looks at.

0 means the current bar which is still forming.

1 means it looks at the value of the last complete bar.

2 means it looks at the value of the 2nd last complete bar etc.

And so on. The example above uses a zero value which means it is getting its value from the bar which is currently forming.

Thanks waltini1 for your reply, appreciated! That's exactly what I was look for. Another quick question, How can i get the Current Period to which the EA was attached, like in your example you are using "PERIOD_H4", I want to run my EA for any period the user selects. How can i get that value?

Thanks!

double Var6 = iMA(NULL, 0, 50, 1, MODE_LWMA, PRICE_MEDIAN, 0);

The easy way is to just put a zero instead of the time period and it will use the time period of the chart to which it is attached. I have changed the example above. Of course if you change the time period of the chart with the ea attached the MA will change with it.

To avoid that you could do as in the example below.

double Var6 = iMA(NULL, TimePeriod, 50, 1, MODE_LWMA, PRICE_MEDIAN, 0);

Then at the top of your ea where the extern's are put

extern int TimePeriod = 5;

This ea will then use the 5 minute bars for the MA and won't change if you change time frames. I used the word TimePeriod but you could write SantaClaus or whatever takes your fancy.

Thanks once again, waltini1. One last question, in my EA if the user specifies the SL to be 10 pips, how should i apply it to different pairs e.g. some pairs have a price with 2 decimal places and some with 4 with the same borker. So for some pair 0.01 is a single pip and for some 0.0001. What is the right thing to do in that case?

Thanks in Advance.

OrderSend(Symbol(), OP_SELL, InitialLots, Bid, 3, Bid + StopLoss*Point, Bid - TakeProfit*Point, "First Sell", MagicNumber, Red);

When typing out your order send see how I have put *Point after the stoploss and takeprofit. the * means multiply and the Point calculates how many decimal places for the currency to which it is attached.

I believe this is the accepted manner so that the same ea can be used on JPY currencies as well as USD.

Watch out for 5 digit brokers, you will have to put 100 instead of 10 for your stop loss.

On the MetaEditor section where you make up your ea to the right is the navigator panel. Down the bottom is a tab marked search. Click on that and type ordersend and hit enter and it will explain all in great detail.

Same for iMA, type iMA and it will show you all the ins and outs of how to change the parameters.
