symbols are the same, and logical flow of program parameters are the same. The difference lies in the calculations and precisions associated with the results. Although the difference appears to be minor, in terms of programming, the two versions are entirely different. Version 1W4D applies to currency pairs with one whole number position and four decimal point precision. It requires that results must be calculated to the 0.0001th precision. This type of calculations applies to most of the major currency pairs like EURUSD, EURAUD, EURCHF,GBPCHF, BPUSD, USDCAD, USDCHF, and EURGBP. Each 0.0001th movement in currency pairs is equivalent to one PIP (percentage in point), which is how profits and losses are made. In summary, Version 1W4D requires 10,000th point precision. Version 3W2D applies to currency pairs with three whole number position and 2 decimal point precision. It requires that results be calculated to the 0.01th precision. This type of calculations applies to currency pairs like the USDJPY and other pairs that have the Japanese yen as member. Each 0.01th movement in the currency pair is equivalent to one PIP (percentage in point), which is how profits and losses are made. To summarize, Version 3W2D requires 100th precision. To allow for the above differences, programming varies accordingly. If precisions other than the two above are required, programming must be altered to meet the needs. |
