MTF entry doesn't work correctly #419438 03/10/13 10:40 03/10/13 10:40

By seeing a plot, 4h exit works correctly but entry is not what I expect, although both plots are correct. I think I am wrong at using MTF and I am not sure that where is scope for TimeFrame so plese correct it. Code: function run(){ set(PLOTPRICE+PLOTNOW); BarPeriod = 15; LookBack = 5000; StartDate = 20121024; NumDays = 5; set(TICKS); TimeFrame = 1; vars Close = series(priceClose()); vars tmp1 = series(SMA(Close,21)); TimeFrame = 16; vars Close = series(priceClose()); vars tmp16 = series(SMA(Close,21)); if(priceClose(0) < tmp1[0]) enterShort(); if(priceClose(0) > tmp16[0] ) exitShort(); plot("SMA15min", tmp1[0], 0, RED); plot("SMA4h", tmp16[0], 0, RED); } Last edited by SFF; 03/11/13 10:48.

But here, I want to enter on every bar if a condition is met on BarPeriod = 15. I want to define TimeFrame for every indicators used in a code. In MTF strategy, it is very helpful to see what indicator used for what time frame. This code is wrong? I defined TimeFrame = 1 here which is on every bar. Maybe It is wrong to use same Close vars in both TFs. Code: TimeFrame = 1; vars Close = series(priceClose()); vars tmp1 = series(SMA(Close,21)); Last edited by SFF; 03/11/13 13:43.
