FXCodeBase.COM: Forex Chart Indicators and Development

Thank you very much in advance for your awesome mentor,

In STRATEGIES
local tk, H0
function ExtUpdate(id, source, period)
if id==tickSourceID then tk = source[period] end
if id==barSourceID then H0 = source.high[period] end

-- now every tick we can compare tick price with bar.high price.
end

Is there an equivalent way In INDICATORS to compare tick price with bar prices ?

Sure, if you use core.host:execute("getSyncHistory" do get your price data.
This is the case with most MTF MCP indicators.

Thank you very much in advance for your awesome mentor.

Is it possible to have a STRATEGY or an INDICATOR applied to MULTIPLE instruments?
(To eliminate having multiple instances of the same STRATEGY or INDICATOR applied to each instrument)

Much appreciated,

Sure. Strategy can trade on different currency pairs.

Yeah, Move stop to breakeven +x pips would be awesome

Your request is added to the development list under Id Number 3967

Thank you very much in advance for your awesome mentor.

Follow up to my previous enquiry to have one single STRATEGY or INDICATOR applied to MULTIPLE instruments? (To eliminate having multiple instances of the same STRATEGY or INDICATOR applied to each instrument)

For example I can implement a STRATEGY or an INDICATOR to EXIT positions of a specific instrument when its RSI indicator reaches a certain level.

But don`t know how to apply it to ALL instruments without having multiple instances of the same (one for each instrument)

Much appreciated,

But don`t know how to apply it to ALL instruments without having multiple instances of the same (one for each instrument)

Give me an example.
Will write this for you.

-- Appling this indicator to to EUR/USD chart will exit EUR/USD long pos if EUR/USD avg[period] crosses below threshold
-- and will exit EUR/USD short pos if EUR/USD avg[period] crosses above threshold.
-- I wish to modify it to work also on an additional another instument say USD/JPY.
-- I mean (I could) but do not want to have another instance applied it to a separate USD/JPY chart.
-- Wish to have ONLY ONE instance to exit both EUR/USD and USD/JPY.
