Overnight swap rates and other

Please can anyone explain IN DETAILS what elements work on market to change overnight swap rates?

I would need a cross with stabile swap rates (long positive, short negative or viceversa). Obviuously this can’t be guaranted for the future but what cross do you suggest with such similar features? Or can you suggest a broker with high gap between long and short swap?
Thanks

hey sabbb....... swap is primarily the interest rate differential between 2 central banks , with you accounts deposit currency being a factor ..... it can differ slightly between brokers .... swap calculators can shed some light.....

ea's, scripts and indicators can display all the swap, both long and short, per pair and then choose the one that interests you..... keep in mind those MarketInfo(Symbol(),MODE_SWAPLONG)) and MarketInfo(Symbol(),MODE_SWAPSHORT)) values might not be accurate..... the classic case of inaccuracy is oanda.......

the central banks rates at the bottom left of the forex news page.....

not being sure what your aim is, my next comments might be off target...... be aware swap for the most part swap is a very minor part of forex......

as example, the eurusd swap for a 10 standard lot short trade is a little less than +400$ a week...... last week, just simply selling at the weekly open and buying at the weekly close would have netted 8000$......

the eurusd weekly price movement could easily be +/- 10,000$ a week...... so it's imperative you have the pairs trend direction right.....

a single months movement against you might be several years worth of swap......h

Thanks for your answer and links.
However you didn't enter in the focal points of the question. I perfectly know that swap is not important in a day trading, but it become important if the position remains open for a long period, in certain trading kinds.
Then the question was: what elements work to produce a change in swap rates offered by brokers?

I'm also wondering: in theory, swap must be equal between brokers, but this is wrong. I am wondering why?
