Show a candle of the middle price of bid and ask

Postby Nikolay.Gekht » Mon Aug 23, 2010 8:16 pm

The simple indicator which shows the candles of the middle price of the bid and ask (open = (bid open + ask open) / 2, high = (bid high + ask high) / 2 and so on).

The indicator also shows the ask high and bid low dots as well as the most recent price. You can apply other indicators as on the bid/ask prices (whichever is chosen in the chart toolbar) or to these midprice candles (see the "Source" tab in the indicator options).

The indicator also shows the current bid and ask prices as a lines.

Is it possible to get a HA version of this?

I believe you already can add HA on chart.
Once you add midprice_nw.lua to Chart.
Ha will use midprice_nw.lua as a source for its calculations.

Hi Apprentice,

I've been doing a lot of Lua learning and have written an indicator based off this indicator. I'm now trying to create a Strategy based off it.

I'm trying to use the indicator_instance profile:createInstance (source, parameters) method I found here.

http://www.fxcodebase.com/documents/Ind ... tance.html

But I can't figure out how to provide a combined bid and ask stream to the indicator.

I can't find a way of getting a combined source directly so have been trying to figure out how to combine the two streams created by
bid = ExtSubscribe(1, nil, instance.parameters.timeframe, true, "bar");
ask = ExtSubscribe(2, nil, instance.parameters.timeframe, false, "bar");

What's the correct way to do this??

Cheers.

local MA_Period=10;
MAofBid= core.indicators:create("MVA", bid , MA_Period);
MAofAsk= core.indicators:create("MVA", ask, MA_Period);
