I can't say about it and i don't have enough information about it but there are many telegrams group even most of them are free, but some are paid. They are predicting even the dip of the coins that at which range you should buy and at which range you should sell the coin.
I wont join that group even if its free because I know, they are the pump and dump group and if you are too slow, expect to lose money so better to depend on yourself and create your own strategy. Many indicators can tell this one, use a multiple one and make sure you understand that, MACD or RSI can tell if the market is already oversold, that could be your sign.
Well, possibly that is a pump and dump group which is also what I don't trust, you don't trust but you can still join since there is nothing lose with you.
Do you have at least references if you will join a group like this but as I always not to follow their instruction. Because in fact, there are no such tools that you are looking for. However, there is no way to predict the market condition, there is always a change from time to time and it does not give an accurate result. Just use your common sense to determine it will become ah lower end.
