Does MT platforms have different types of tick data?

<p id="isPasted">Essentially, what's happening is the testing software makes your 1M OHLC backtest look a LOT better than real results because there is a flaw in the software that interpolates what happens between those 4 values (OHLC). So, in most cases when you have an open order the testing software 'gives' you a perfect entry, right at your asking price, it also gives you a perfect exit, even if it doesn't have the data near your TP or SL.</p><p>The best way to explain this is like this: If have have an M15 candle, that is 15 pips in total size (high to low). There are 4 values associated with those 15 pips, OHLC. Let say you placed a trade at the open of that candle and had your SL 5 pips from the entry and a TP was also 5 pips from the entry. Using OHLC data the backtesting software will likely tell you that your TP was hit and not your SL, even though the SW does not have the data to definitively tell you. It's just randomly generating data inside that 15M candle between the OHLC.</p><p>Some parameters can be found using 1M OHLC, but anything that dictates TP or SL (Trailing stops) should be optimized and testing on Tick data.</p>
